Re: '64 C-10 Stalled Project Rescue
 

Yeah, the stance is about perfect for a resto-cruiser. The truck was lowered by the PO before I bought it. The suspension includes a POL panhard rod and front sway bar, so I'm assuming the springs are from POL as well. Although the shocks appear to be CPP with the red poly bushings. So I suppose the springs could be CPP also. No real clue on how much each end was lowered, I don't think there are any identifying marks on the springs.

In a perfect world, I'd prefer drop spindles up front instead of springs for more suspension travel. But I'm probably not going to change that now as it looks good, and the ride is fine on normal roads.

Thanks Arne. Truck looks great.

Re: '64 C-10 Stalled Project Rescue
 

I spent some more time testing and fitting the various steering pump parts to the engine today (while iced in by freezing rain overnight), and I'm pretty certain I've got a handle on what I need for this to all fit and work. I'm not going to detail it all here a second time, you can read it if you wish in the thread I started for this in the main '60-66 forum - https://67-72chevytrucks.com/vboard/...6&postcount=11

Short executive summary - the pump brackets from POL did not fit my engine correctly, and the 2-row pulley from POL apparently only works with their pump brackets. So I am going to need to buy a 2-row pulley that is built to GM specs, not POL's.

Will possibly go ahead and buy the 3-row crank pulley I will need when I add the A/C later. Might as well get all of this in place now while it's all fresh in my mind.

Re: '64 C-10 Stalled Project Rescue
 

This is one of those times where I would buy a junkyard engine with serp belt and AC brackets etc. That way you have all the brackets, pulleys, etc and then can sell the long block or save it for a future project.

Re: '64 C-10 Stalled Project Rescue
 

Back to the A-833 Chrysler/New Process transmission for a moment- I have some additional questions:
1) Does it mount up to the original '64 C10 trans mount/crossmember?
2) Shifter linkage? Hurst/Chrysler/other?
3) Bellhousing and clutch?
4) Slipyoke spline to GM driveshaft?

We may need to discuss off-line if becomes too much detail, I guess I missed the part where it got installed etc. I'm somewhat ignorant about these old trucks but have sufficient mechanical ability and curiosity to figure them out with some assistance. Thank you for sharing.

Re: '64 C-10 Stalled Project Rescue
 

Please bear in mind that I bought the truck with this gearbox already installed. My understanding is that it is a matched pair with the early '80s 305 small block in the truck now. I did a fair amount of searching to pick up more info on this, but please don't make me swear to any of this, as some is hearsay.

1) Does it mount up to the original '64 C10 trans mount/crossmember?
Not sure, but I was told that the crossmember is the same as would be used with a TH350.

2) Shifter linkage? Hurst/Chrysler/other?
The linkage appears to be the original from the donor Chevy truck, based on the '80s Chevy shift knob it had on it. I've read that the Chysler linkage is different, with some links reversed on the GM version to allow 3rd gear to be the direct 1:1 gear instead of 4th.

3) Bellhousing and clutch?
The bell housing is apparently special to this transmission. The clutch is probably whatever Chevy used for this application.

4) Slipyoke spline to GM driveshaft?
Yes. Like the crossmember, I was told the slip yoke (and even the overall length of the transmission) is a direct swap to the TH350.

I've read people who have (or are looking for) this box sat that when searching, you want to find the gearbox with it's bell housing and original linkage. Vastly simplifies the swap.

Re: '64 C-10 Stalled Project Rescue
 

Sounds good. Thanks for the detail. It's nice to see somebody keeping a clutch-pedal in use. As long as my tired old knees hold up, I figure to do the same.

Re: '64 C-10 Stalled Project Rescue
 

The guy I bought it from had a fresh aluminum head 355 and TH350 that he wanted to sell me for the truck as well. I decided that the little 305 with the unusual manual gearbox was more in line with how this truck will probably be used. Nothing about it has prompted me to second guess that decision so far.

Re: '64 C-10 Stalled Project Rescue
 

Not much going on with the truck right now, as I'm waiting on parts. The remainder of the new steering rack kit has not shipped yet. And a small order of some interior bits has been delayed by weather. So I wait...

Re: '64 C-10 Stalled Project Rescue
 

Started working on the interior today. Finally installed the inside door panels, and began fitting carpet. Should finish the carpet tomorrow, then will look at the seat refurbishment prior to reinstalling it. Pleased so far.

Attachment 2244756

Re: '64 C-10 Stalled Project Rescue
 

Finished the carpet install today. The fussiest part was trimming the carpet around the shifter so that the rubber boot is under the carpet (to seal moisture away from the carpet and padding) but with the carpet edge still covered by the trim plate. I'm pleased with the result.

I've started working on the seat now, have the replacement side support spring in place, and have just a couple little tweaks left to secure it. Then I'll strip the original covers off and assess the condition of the foam.

Attachment 2244998

Re: '64 C-10 Stalled Project Rescue
 

Seat spring repair is completed, but while the foam cushion looks pretty good it is very soft where the driver's arse sits. So new foam has been ordered. Should arrive early next week.

I've received a shipping notice on the remaining parts of the rack & pinion kit, it should also arrive early next week. I've also ordered a used factory GM 3-groove crank pulley to accommodate both the new power steering and the future A/C. It looks like I can use the current 2-groove water pump pulley for now, but may need a different one (different groove spacing) when I add the A/C.

So not much will happen for a while, until some of this stuff arrives.

Re: '64 C-10 Stalled Project Rescue
 

A little bit of cooling system work today, some temporary, some more permanent.

I drained the coolant to work on the thermostat housing and water neck. The 305 with the Edelbrock manifold had no place to install the early-style 2-terminal temp sender (for the dual Cold-Hot idiot lights), and I didn't like the angle off to the left of the 80's water neck. So I bought a simple forward outlet water neck and a 1¼" thermostat spacer with a ½" NPT port for the temp sender. That all went together fairly simply. While I had it all drained I bypassed the heater so that I can remove the factory system in anticipation of the future A/C system. I suspect I'm going to need to prep and paint the firewall where the heater sits, as it looks like the painter did not pull the heater prior to painting the engine compartment. Will be working on that later.

Tested the temp idiot lights, and the Cold light works properly now. Obviously didn't intentionally overheat the engine, so I can't verify that the Hot light works, but I see no reason now that it wouldn't. Maybe I'll go point my heat gun at the sender, that might do it...

Re: '64 C-10 Stalled Project Rescue
 

The power rack and parts arrived today, as FedEx Ground is running Sunday shifts to catch up from the holidays?

In any case, it looks great. I don't know how soon I'll get to it as our place is in serious disarray with people arriving tomorrow to replace 2/3s of the flooring. But maybe I can get started on it next weekend.

Attachment 2247147

Re: '64 C-10 Stalled Project Rescue
 

That looks so damn familiar lol Do not over think the install! It is really very easy!
I did get the steering completed and installed on mine. I had to use 3 - 3/4" DB D Universal joints, one Heim joint and a mount a bought from Unisteer, and about 3ft of DBL D steering rod. Just a heads up, the damn joints are not cheap, but I got most of the stuff off of Amazon, along with a 5 or 6ft section of DBL D for a really good price. I'll have a bunch of pics coming of the routing and placement. Remember, check your power steering pump locations in regards to the rack universal joint.

Re: '64 C-10 Stalled Project Rescue
 

Yeah, I'm a little concerned about the column angle and u-joint clearance. But won't know more on that until I get started. I've been hoping that I won't have the same headaches there that you had, but since the base trucks are similar...

Re: '64 C-10 Stalled Project Rescue
 

This is the install instructions from Uni-steer that I used for examples and parts. Hopefully it loads here.

Re: '64 C-10 Stalled Project Rescue
 

last of them...

Re: '64 C-10 Stalled Project Rescue
 

Just so you know, I bought the Heim Joint Mount they have, BUT moved it back to the back two bolts rather than the front two (Both used the same middle bolt)

Re: '64 C-10 Stalled Project Rescue
 

Yeah, I downloaded a copy of those directions from Unisteer a while back. Oddly, I've read through the instructions that came with the POL rack, and they make no mention of cutting the OE steering shaft. They mention the possible need to shorten the new intermediate shaft, but nothing about the OE shaft. I find the discrepancy to be a bit odd. It will be interesting to see what I run into when I get into this. I'm prepared to cut the OE shaft if necessary, but it would be great if I don't have to.

Re: '64 C-10 Stalled Project Rescue
 

I wished I had more info for you on this, but I am going with an aftermarket steering assembly. Just from what I seen and found, the longer the shaft is coming out of the firewall, the worse the angles get when you add in the universal joints. This may not make sense yet, but maybe as you start the process you will see what I found. If by chance you do not find that this is the case, please elaborate on what you find. I fully understand your concern cutting the original shaft! that would make me nervous also.

Re: '64 C-10 Stalled Project Rescue
 

Might get to this over the weekend. If not then, it may be another week or so beyond that.

Re: '64 C-10 Stalled Project Rescue
 

New seat foam arrived today, and it is very nice. I'm hoping to get at least the seat cushion recovered this weekend, maybe the seat back as well. So probably won't start the steering conversion this week.

Re: '64 C-10 Stalled Project Rescue
 

Really pleased with the fit and feel of the new foam. Makes it easy to build a nice seat. The cushion is done. Backrest sometime this weekend.

Re: '64 C-10 Stalled Project Rescue
 

This looks nice and comfortable

Re: '64 C-10 Stalled Project Rescue
 

Well, the backrest isn't going as well.

The PO bought the seat covers and carpet to match (dark saddle), but it turns out the covers are for '67-72. While the seat cushion cover fit the '64 frame nicely, I did notice some quirks. The fit of the '67-72 backrest cover over the '64 seat frame is rather fussy. I wasn't satisfied with my first attempts. I've got a new approach in mind now, so I'll keep at it and report back later.

Re: '64 C-10 Stalled Project Rescue
 

While taking a break from the seat backrest upholstery this morning, I took another look at the steering pump mounting. And after a bit of head scratching and tweaks, I'm pleased with it all now.

Getting this all sorted was a lot more hassle than I expected. GM must have equipped millions of long water pump small blocks with both power steering and A/C. So getting everything to fit and line up is not cutting edge stuff, but should be very routine.

Here's what I came up with in the end:

• Saginaw pump for bolt-on pulley (Performance Online)
• Steering pump bracket kit for long water pump (Alan Grove Components, #402L)
• Aftermarket factory-spec 2-groove steering pump pulley (GM #3941107)
• Used factory 3-groove crank pulley (GM #3972180)
• Existing factory long water pump 2-groove pulley (standard early '80s GM part)

Even with all this, mostly factory parts, I had to re-engineer the pump mounting a bit. While AGC says their parts are designed to use factory pulleys, when I mounted the pump per directions, the groove alignment was not correct (too far forward by about ½ a groove). Luckily, the design of the AGC brackets allowed me to substitute different spacers to move the pump back about 5/16". That made it all work.

Will be moving on to the rack and pinion mounting soon.

Re: '64 C-10 Stalled Project Rescue
 

Well, today was more than a bit disappointing. A whole lot of things not going the way I'd hoped or planned.

Now that I had the steering pump mounting and various pulleys sorted, I began fitting the rack & pinion itself.

1st issue — The factory GM 3-groove crank pulley doesn't allow the rack to fit in place. The factory 3-groove pulley (GM #3972180) has 2 inner grooves at 6¾" diameter, and the outer groove is bigger, at 7¾". That bigger outer groove hits the rack tube.

Temporary solution — I put the original 6¾" 2-groove crank pulley back on. I don't need the 3rd groove until I add A/C in the future, and 3-groove aftermarket pulleys with all 3 grooves at 6¾" are available.

With the original pulley back in place, I mounted the rack to the frame. That went fine, it fits up exactly as it should. But it also brought additional issues to light.

2nd issue — The lower U-joint on the new steering shaft won't clear the newly mounted steering pump.

3rd issue — Despite no mention of this in the instructions from POL, the steering shaft will need to be cut short near the firewall.

4th issue — Not only will the shaft need to be cut, it will also need to be modified at the cut end from ¾" round to ¾" DD so that the U-joint can be attached.

Issues 3 & 4 are annoying mostly because POL made no mention in the instructions about this. I suspected that I'd need to do both of these, but hoped otherwise. It looks to me that if I do this right, I should be able to make the shaft work without having to use a third intermediate U-joint, but I can't promise that just yet.

Issue 2 is a lot more troublesome, and was also reported recently by member 88Stanger. It looks like there are really only a couple of paths forward. One is to use the later Type-2 Saginaw pump with remote reservoir. The other would be to convert to an electric pump instead.

Both options mean starting from scratch on the pump stuff. Pretty annoying given the hoops I jumped through to get the pump to fit and line up properly.

The later style pump has the advantage of being fairly traditional, and a known quantity. But given the pulley alignment headaches I've had so far, I'm not convinced that it would be a simple fitment. And 88Stanger reports that the frame needs to be trimmed for hose clearance with the Type-2 pump. The price tag would also be significant. Pump, reservoir, brackets and pulley will easily be $400, maybe even $500.

The electric pump (typically Volvo, possibly Mazda or Mini) can be picked up pretty cheaply from salvage yards, and is not really large, so there are multiple mounting possibilities. But they do draw significant power, and might need an alternator upgrade, depending on what the later unit now in my truck can deliver. But even with a bigger alternator it will probably be considerably less expensive than a new Type-2 pump and bits. And without a belt-driven pump, no pulley changes are needed for later A/C.

So I'm on hold for a bit while I continue to research pump choices.

Last note - While POL rack & pinion kit is still a decent option, the pump clearance issue is a big caveat that people need to be aware of.

Re: '64 C-10 Stalled Project Rescue
 

Man, that's a bummer on the fitment issues.
Is your engine mounted in the stock, v8 location, or is it moved forward on the frame some? I wonder if maybe some of the fitment issues you're running into is from the engine being further forward on the frame than stock?

Re: '64 C-10 Stalled Project Rescue
 

I'm pretty sure the engine is in the stock location. In fact, most indications are that it was a V8 truck from the start.

I don't believe my fitment issues are unique. 88Stanger has posted the same pump clearance issue with this rack kit in his build thread.

Re: '64 C-10 Stalled Project Rescue
 

Are you fully committed to the rack and pinion conversion? Seems like another option is to switch to a power box from a square body truck and return the POL kit.

Re: '64 C-10 Stalled Project Rescue
 

That's a good question. Had I known about the pump clearance issue prior to placing my order, I might have gone with the square body conversion. But only due to the pump clearance issue, as the square body 'box still typically requires some additional mods (to column and new holes in frame), and I'd have wanted to replace all the steering parts with new anyway. I do like the idea of the modern rack steering precision, so I might still have ordered the rack kit, although I wouldn't have spent the time, effort and money on the pump, brackets and pulleys.

Besides, I don't know how much arguing I'd need to do at this point to return it, as each rack is custom fabbed to order. It's not worth it to me to pay return shipping and maybe a restock fee to start over, given that there are ways to make it work.

After doing more reading last night, I'm pretty sure I'm going to try the electric pump solution, probably mounted inside the left fender well.

Re: '64 C-10 Stalled Project Rescue
 

After further review, I'm definitely going to go with the Volvo electric pump. I plan to get one coming later today. I will need to either modify the Volvo bracket or fab up a custom part for mounting, and also get a metric M16 to -6 AN adapter, but it should be straightforward to mount and hook up. The wiring is simple, just 3 wires (a 12 ga. to battery positive, another 12 ga. to chassis ground, and a wimpy wire to switched ignition). Done that way, the variable speed of the Volvo pump is in "limp home mode" and runs at a fixed 70%.

There are aftermarket controllers available to change that—one is just a simple manual rheostat knob adjustable from the driver's seat, anything from 0-100%. The other is rather cool, it is automatic based on the speed of the truck, and includes a GPS sensor to determine how much boost to provide. Full boost at low parking lot speeds, to minimal boost on the highway. Sounds cool, but I'm just going to start with the fixed 70% choice, and one of the controllers can always be plugged in later if desired.

I have the rack itself mounted in place. The steering shaft route is fairly clear and shouldn't be too difficult, now that I've eliminated the pump clearance issue. I will need to make a couple of small relief cuts just to ensure good clearance, but nothing major.

The mechanical part of the steering conversion is now complete. Everything is bolted up and all is working well. The wheel turns lock to lock smoothly and no binding.

As for the hydraulics, I'm ordering the Volvo pump this evening.

Re: '64 C-10 Stalled Project Rescue
 

Thanks for sharing all the info on the POL kit mine just arrived and I’ll be installing it in a few weeks.

Hopefully I won’t have as many issues, I’m using an Ididit column and LS engine.

Re: '64 C-10 Stalled Project Rescue
 

I don't think the Ididit column should add much in the way of problems. If the column is longer under the hood than stock, you may need to add a 3rd U-joint and shaft support bearing, but otherwise it should be similar.

POL notes that you can't use a low mount alternator or steering pump with an LS. I don't know what other engine driven pump options there are for those engines, so I don't know if you'll need to use an electric pump or not.

Re: '64 C-10 Stalled Project Rescue
 

My Ididit column (automatic, column shift) shown. Should be doable.
