Re: Spring Swap Thread - 1963 K15
yep, i believe so sir. also, dont forget to look in on ORD's zero rates as they have the pin locater for moving the axle 1" and 1 1/2" with a pin locator for getting the wheel well/axle positioned just right. they are 1" tall tho; but would be an option if a little rear end leveling as well as slight for/aft adjustment of the axle positioning is needed.

Re: Spring Swap Thread - 1963 K15
Not much progress in the last week, Ive been working like a dog at my regular job. Between that, Little League playoff / championship games and practices and end of year grad stuff for my older one, there has not been a lot of time. I did however manage to bring home a new member of the family for about the price of re doing the brakes on the Dana. Not sure why Im so stoked to have rear discs since the old drums always worked so good. Parking cables seem to be intact. Im pretty sure that the 10 41 stamp on the ring gear means 4.11. I think I may miss the Trac Lok in the 60 since this one is definitely open. One thing I will say about this axle... it is WAY burly!

After some careful examining and comparing posts and pictures, it actually has a Gov Loc. Not really having a lot of experience with the 14BFF, I have some mixed feelings on this as I have heard them referred to as "Gov Bombs" and it seems as though people avoid them like the plague. The 60 had a "Trac Lok" which Ive read wasn't the greatest either but seemed to do really well for what I do. So what are your opinions on this? I did see one mod where a guy lightened the weight(s) inside of the Gov Loc in order to "lock" it earlier (I don't think it completely locks though?). He did this BC from what I read, the GL is supposed to lock at 15 mph difference between wheels which to him seemed like a pretty big shock load to the 3 pin spider? He thought that locking it earlier would lower that shock to the spiders. Again, for what I do with my truck, I have a feeling that it will probably be fine but I do like to understand how things work before I use them so I welcome any info and or advice. Any way it works out, Im still pretty excited to have what appears to be a fairly new axle that has been sitting for the last 5

Re: Spring Swap Thread - 1963 K15
Spring perch spacing on a SRW 14 bolt from 73 to 87 will be 42.5" on center, not sure about the newer models. Stock spacing for 60-72 is 40" on center. Shock mounts will be in the wrong locations too, and one will be facing the rear. Parking brake cable setup will likely be different. Also you may need to change something with the proportioning valve, resresidual vakve or master cylinder for the rear disks; Not sure what you have in there now.

Re: Spring Swap Thread - 1963 K15
I have the feared gov-lok in my Big Ugly pickup. Never had any problems so far. But then again I don't hammer it offroad, just low and slow.

Re: Spring Swap Thread - 1963 K15
The 3/4 ton dana 44 is roughly 69". I was asking because I had given thought to pulking the 14 bolt out of my burb in favor of a dana 60. The 14 bolt diff is so huge that ground clearance is terrible with anuthing smaller than 35" tires, and I only plan to run metruc 32"s. Downsides were 1/2" wheel studs, narrower track width and of course smaller axle shafts.
You say your axle is from an HD pickup? Could it be an AAM 11.5 even? I'm not real savvy on the visual differences. Either way, nice score!

It is a AAM but it does have the 10.5 ring and the removable pinion support. I think I read somewhere that the 11.5 version does not have the removable support. I just realized that I think I misunderstood Steve on the differences in pinion length in that the 60 is about 1 1/2" longer than the 14B that I have. Oh well, Ive got a good driveshaft builder not too far away in San Jose.

Re: Spring Swap Thread - 1963 K15
4.10s now after I swapped in the big hub dana 44 and 14BFF. I drove a distance to get these because the guy said he was sure they were 3.73 gears, but when i got there and pulled the covers they turned out to be 4.10s. Now overdrive is a must.

Re: Spring Swap Thread - 1963 K15
So do you think you'll re gear the axles or run the 4:10's and swap the rear to a 60? I think these days with the availability of OD transmissions, Id run OD on everything I have regardless of the ratio! LOL. Im still really liking the 4500!

Re: Spring Swap Thread - 1963 K15
I have another nv4500 and round pattern np205. So I'll most likely stick with the 4.10s. Plus its powered by a little old 327 so I probably need the gear.

Re: Spring Swap Thread - 1963 K15
Guess its time for an update. Been working 9 pm to 1 pm for the last few weeks so it hasn't left a lot of time to add to this thread. I finally got the Miller working well enough to lay down a couple of passes and get cross members in for the gas tank supports, re weld the gas tank straps, and move the brackets on the 14bff. My buddy Dozer kept me company the whole time. He doesn't seem to mind the air tools and welder. Please don't hate on the welds though. That was flux core. The solid core with gas came out a little better for the little machine.

Re: Spring Swap Thread - 1963 K15
Finally made it to Twainharte a few hours ago for a little R&R. Had a few already so if this gets askew, don't hesitate to get me back in line. LOL. After much debating (with myself), I finally got the nerve to drill the mounts for the spring hangers. I was in a little bit of a hurry BC I was trying to get it done before I went back to work. I may not have too many pics.
One cool thing that I was able to do was to adjust the TC. It was a few degrees off center. I was able to weld in an adjusting nut so that I could adjust it to where it was centered and keep it there. Hopefully the weird vibration that has been bugging me will go away!

Re: Spring Swap Thread - 1963 K15
I got the spring pads, bump stops and shock hangers cut off of the 14b and got it into place. Lots of measuring later, I was ready to set the new pads and the reworked shock mounts. I did have to get new 5/8" u bolts and plates for the tops of the springs. The plates are crazy thick (3/8") and are really well built.

Re: Spring Swap Thread - 1963 K15
I used the front hole on the spring pad and the top plate in order to move the axle back 1".

where did you get your new perches and top plates? my local offroad shop is out of them at the moment so i might as well order some. do you think the rear hanger will interfere with using a modified drop hitch or bumper brackets? i'm wondering if i should use my 2000 model springs for better clearance? anyways nice truck and pit! my pits 15 yrs old and always been a great shop dog,rick

Re: Spring Swap Thread - 1963 K15
That stance looks great. Did the 52" springs lift the front at all, or is it close to stock?

Re: Spring Swap Thread - 1963 K15
The front ended up almost 1/4" higher which is really nothing. The rears on the other hand lifted the truck 2 or so inches compared to the stock springs. I'm really hoping that the weight of the be will bring it back down

Re: Spring Swap Thread - 1963 K15
Do you still have enough clearance between your front driveshaft and the bellhousing where the clutch slave sits? I'm assuming the 52s are much more flexible than the stock front springs.
Do you have the bed back on and fuel in the tank? I'm curious what your measurements are from the ground to the wheel well lip at the centerline of the front and rear axles.

Re: Spring Swap Thread - 1963 K15
I still have the front driveshaft out since I put in the 205. The 205's output is higher than the 221 so the DS actually almost hits the trans cross member. I'm looking for a new one or may even modify the one in it to fit.
As far as the bed, I still need to run the fuel line and connect the e brake cables first before I drop the bed onto it. Hoping by the end of this week.

The weight of the bed and fuel will bring the rear down some.
