Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Perhaps heat the sway arm and clock (bend) the end a little to reduce the angle between it and the upper A-arm. High misalignment spacers would work but I would think the other option would be better.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Have you spoken to Rob since it is his frame/suspension design about the problem? it might be something he has not seen yet or may even have a fix for it...

Not yet ... he is very hard to get ahold of during the summer as he goes to many events on the weekends (and starts on Thursday/Friday). For example, I think he's in Missouri at the NSRA event there this weekend. The easiest way in fact is to find him at an event. I talked with him a bunch at the C10 Nationals. Once I give this slightly mod'd setup a try I'll at least shoot him an email with what I found and what I did since a recent photo from the shop shows some of the chassis setups still use the same bar arm on the 3 piece front bars so it would seemingly have the same problem.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
I'm sure that at no limit's scale each chassis is different and they are always evolving, so letting him know is pretty likely to result in some positive changes to their builds.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Oh, and another follow up... leaky 3rd member.
So I tore the rear end apart (this time I decided to go way down and pulled the brakes off to re-align the calipers a little better) and went to town. I decided while I had the 3rd member out I'd throw some paint on, so I did that first. On to the leak. Turns out is was leaking from the gasket for sure and I wasn't quite sure if it was also leaking from the stud. So on re-assembly, I decided to just do RTV on the gasket first. So I applied some black RTV in a very thin layer to both sides of the gasket. Installed the 3rd member, but did not reseat the axles and left the driveshaft disconnected and just hand tightened all the nuts to where they were snug. I then let the housing sit one hour before torquing everything to the 35 ft-lb spec. After torquing, I let the housing sit for a good 14 hours before I filled with fluid. Once I filled it with fluid I figured it would be about 2 hours before a leak started if one where to start (based on the last time I did this). Sure enough, it was leaking. Although this time I got lucky and as I crawled under the truck I got to witness a drop of fluid seeping out through the threads at the end of the nut. Not even through the split in the lock washer, but through the threads. Grrr. So mod to this round, I pulled the nut, lock washer and copper washer on just that stud. I then put black RTV on both sides of the copper washer. Since this isn't inside the housing, I was very liberal with the RTV. I put the copper washer back on then put a gob of ARP thread sealant on the stud and put the lock washer/nut back on and re-torqued. I did this whole procedure very fast as the drip was at a rate of about one every 5 min, so I had limited time before more oil started to mix with my uncured RTV. Well, so far so good. No leaks and I've gotten 2 thermal cycles on the rear end (get it hot by driving then let it cool). I'm still not 100% on this solution but it's working for now. If it start leaking again I'm going to need to take a real close look at the interface between the stud head and axle housing to see why it is leaking. We run metal to metal joints all over the jet engines I design and we don't have leaks on joints with upwards of 800 psi on them. Hmmm. Ok, now rant, there are 4 studs below the fluid line, why this one leaks and the other 3 do not is beyond me. Frustrating for sure as it is a PIA to be pulling the 3rd member every couple weeks. But it's just ammo against my Ford buddies. Only leak I have on the entire truck is from the dang Ford part (of course none of it is Ford parts, but it's still a good jab).

An update ... after a few weeks, about 100 miles or so, no leaks! Still dry under the reared. I'll be honest though, C10CJ has been sitting now for about a week and a half. Had a family reunion this past weekend and just plain been busy with work and getting myself back in shape. But should be getting the truck out some this weekend. The other reason the truck is sitting is I've been mulling over what to tackle next. Here's the short list: -Add power steering cooler -Change trans cooler over to plate style for better efficiency -Bed Floor / mini-tubs Also, I did toss together a video a bit back on painting the 3rd member. Nothing special but I show you how I made a very simple paint mask to protect the gears during paint and the process I used to paint, which tends to work well for me.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Question for you Chris, how much clearance do you have on the front coil springs to the shock plates? I have a no limit frame like you only i got viking double adjustables instead of ride techs. I have only about a 16th of an inch clearance and im worried it will make contact while driving.
Im no where near your progress but i really appreciate how thorough you are with what you post.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Hey guys, a little video I tossed together from last weekend's cars and coffee here in CO. This one is getting huge. It's hosted by Adam's Polishes and is starting to draw cars/trucks in from the entire Denver metro area. I met the new owner of the truck SS01 (built by squarebody syndicate, the one that sold on auction for >100k) a couple months ago. Also met another board member who also lives here on the north side of Denver.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
I didn't realize that was so close to me now. I moved to Grand Island NE last year. I may have to make it to the next one with one or both of my trucks.
Defiantly looks fun!

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
That might be a bit of a hike for an informal show ... but, if you want something more formal, then GoodGuys is in Loveland, CO Sep 7-9, and I'll be there! Last year they said they pulled in close to 2500 cars. I have no clue what the numbers will be this year, but over 2000 seems to be consistent for that show.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
... and sorry for the lack of updates. August was a very busy work month. September is shaping up to be a busy month in general.
The short list of stuff to be done (some of this has been on the list a long time, lol): -Add a small cooler to the power steering -Change the trans cooler over to a dedicated unit (man, this is harder than you think, I don't have a good place to put the unit I'm looking at) -Bed Floor -Center console The long list -Thinking about some nice bucket seats to keep my rear end firmly planted -Interior cleanup work (dash pad is painted), door panels and visors need repainted. Door panels need new fabric. -At some point I need new carpet And don't forget I'll be at GoodGuys Colorado Sep 7-9 if you're in the area.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Funny, I just bought a Derale 13215 power steering cooler and a Derale 13403 stacked plate trans cooler before checking my subs here. eBay has a 15% off sale today so I took the opportunity to get some stuff on my list!
The Derale trans coolers are nice, made in USA and sport AN6 fittings.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Good stuff man! I was just checking out coolers tonight. Looking at the Earl's coolers and then tossed in the Derale coolers. Man the Earl's are expensive.
I'm actually looking at the Derale 13740 (similar to the EARL's FP820ERL, but half the price) for the trans. I am thinking of moving the trans cooler to either the bed (under the bed floor in the front) or under passenger side of the cab. I want to decouple the trans cooling from the radiator completely, meaning I don't even want the hot air from the trans cooler entering the radiator flow. Their power steering kit is interesting too. Much more cost effective as well. Thanks for the pointers!

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
I'd love to put the trans cooler under the cab but I'm worried about airflow vs. cooling capacity. Ah, I see the one you're looking at comes with fans -- that crossed my mind but I thought I'd avoid the maintenance associated with small electric fans... but now I'm having second thoughts
That Derale cooler is stacked plate, which is more efficient than plate and fin. Looks like a pretty good deal compared to the Earl's option!

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Just came across a cool mount last night. AZProPerformance just came out with a new line of parts (or so they said on Facebook... It's branded React Suspension) and they happen to have a remote trans cooler mount made for the derale 13740 cooler:

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
I kinda wish I'd have bought the 13740 now! I like the idea of moving that weight back and saving some space, and using shorter lines. I was thinking about mounting it to the frame and floor with standoffs actually, in about the spot that React mount sits.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
I'm gonna make you really jealous now crakarjax ... 13740 ordered
I also ordered an Earls temp-a-cure 10 row narrow for the power steering. I went that direction so I can compare the build quality between Derale and Earls. I'm going to see if I can get the power steering cooler installed before Goodguys. I'll also make an attempt at the trans cooler, but that one requires me to do some mods to the wiring which requires some surgery. So that may get bumped post Goodguys. And Duane, thanks for the link! I saw that mount in a Pro Perf FB post and wondered what the heck it was! I may have to leverage that if I decide to put it under the cab, but I was actually thinking I'd mount it fans facing the ground. I'm still trying to decide between under the cab and in the bed. Once I get the unit I can then hold it in place and see which location I like better. I looked from the bed forward and it's a straight shot to the cooler lines right along the tunnel. I was pleasantly surprised by that. So I may hard line it from the front of the tunnel all the way to the cooler, then just use some Pro-Lite 350 from the trans to there to allow for trans movement. Thanks guys for the feedback! This will get interesting for sure!

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Forgot to tell you guys ... I got invited to participate in a charity photo shoot (well, C10CJ in reality). The photographer is putting together a calendar of classic cars and models to sell and raise proceeds for charity. I took some shots with my iPhone, but since it is an iPhone the photos aren't the best due to where the sun was positioned. We're told we get copies of the photos from the photographer so I'm looking forward to some of his pics. In the meantime, here ya go, and I hope C10CJ gets selected for the calendar (there were more cars than months).

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
oh man, what a busy week it's been. Started off with a trip to SD to help a life long family friend (he's family) with his 700R4 that wasn't shifting into OD. We pulled the 2-4 servo and cleaned that up (since he had every other gear and no slipping I was suspect he had a stuck 4th apply piston). We got it all cleaned up and it shifted into OD on the first try of the test drive, but then never again. I also found his TV cable wasn't quite right. So he's got some parts on order. We'll fix the TV cable but I'm wondering if he's going to need a replacement "super servo" 4th apply piston as his was kinda "stuck" in the cover when we pulled it.
Then it was back home to install the power steering cooler. And trans cooler. Yep. I got them both done. I deviated a little from my plans on the trans cooler. I wound up mounting it right behind the front bumper since I could easily route plumbing here w/o having to move my trans temp sensor (which feeds the ECU which controls the cooler fans). So I came up with some simple brackets for both the PS cooler and the trans cooler. Let's get into it. If you follow me on FB/IG, you may have seen these pics but not much description. So a bunch of parts showed up right before I headed to SD so I was ready to get installing when I got back home on Labor Day. As I mentioned, I got the Earl's Temp-O-Cure for the PS cooler as I wanted to compare the build quality to the Derale unit. Here's a shot of the Earl's on top of the Derale. Both are nice build quality. For the PS cooler, I built a bulkhead that I used to then hook in to the power steering low pressure circuit. I just used some 1/8" plate I had left over from the shifter housing build. These are -6 AN bulkhead fittings since the existing lines were -6 and I was using 3/8" hardline to the cooler. I then wound up adding some triangular gussets which you can see in the next pic. I did space the bulkhead fittings so I could get wenches on them. Here's all the brackets for the PS cooler setup. The small one is the bulkhead and the 2 large ones mount the cooler. I built the cooler mounts to give me a 1" space behind the cooler to the radiator support. No fans on this cooler and mounted off to the side of the radiator as I really only need the cooler when I'm running around the AutoX course. Here's the brackets mocked up on the cooler.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Here's a mock up shot showing where I was planning to put the cooler. The front of the truck is kinda up and slightly to the right in the pic and you're looking down between the radiator support and grill, just to the left (driver side) of the radiator.
All the brackets painted up pretty Time to get things mounted and assembled. Two days out from Goodguys CO and I tear the front of the truck apart. The pic isn't the best, but the PS cooler is mounted in it's spot (just to the left of the driver side headlight in this pic). Blends right into the radiator support. That white Earl's box in the part shot in the previous post was the 3/8" steel coated hardline. Comes in a 25' coil. I then have a home built "straightener" to get the lines mostly straight. I then custom bent the lines to fit between the bottom of the radiator support and the frame and then tie in to the bulkhead that I mounted on the frame in the proximity of the power steering pump. Here's the resultant lines. I have the 37 deg flare setup for my awesome flare tool so I go straight from the hard lines to -6 AN. You can see the tube nuts in the pic.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Sounds like a blast, can't wait until I actually get to do some racing with mine!
Are you running the trans cooler lines through the radiator as well, or just the derale cooler?
