A buddy and I just finished up the 63" spring swap for my truck yesterday. Took a full day to finish up. Went fairly well. The hardest part of the project was grinding and pounding out all the rivets. And that wasn't really hard, just time consuming and miserable. The only thing I'm not really happy with is the shackle angle, alittle too steep I think. Shackle is 6.5" center to center. Thats easy enough to change though. After some testing of course... Might not even mess with it. The wheelbase ended up exactly where it was before the swap at 108". I'm prolly gonna go for another 1.5-2" or so with new redrilled and turned spring perches. On to the pictures- I still have some work to do on the booty fabbed shackle mount, gotta "un-booty" it and make it look good. Other than that it's done.
