Giant post I copied from Jungle's forum over on RCC. If you're interested in the specifics of making a 56" leaf swap work with his stuff.
"I pulled the springs and shackles off my RC frame to replace the ones on my truck. I turned it up enough that it was wasting the blocks/springs I had on there. I'm gonna go ahead and say the frames of the pickups and RCs must be hella different.
I started by hacking off the whole passenger leaf and hangars from the frame. I bolted up the rear drill pattern and drilled of the new holes, bolted up the rear hangar, and pretty much pulled the rear driveshaft in two trying to get the leaf to sit on the axle right.
You can see here how much I had to bring the rear hangar forward in this pic, the holes are drilled where the template said they should be it's almost a the full width of the shackle forward. It's obviously not Jungle's fault, since this wasn't the frame his kit was made for, I just found it odd how different these frames are that I thought were so similar.
You can see that one of the holes from the drill pattern almost lines up, I used it to locate the rear hangar in the same place on each side.

I'll get some more detailed pics of the forward mounts tomorrow, I only had to cut off one of the bed mounts, do some messing around with the ebrake cable mount, and notch the crossmember towards the front of the bed. Nothing too structural.

Still sits right even of my old rear leaf setup, which was a mixup of my 3/4 ton pack, an RC pack, and the stock 3" block, with my own hacked up shackle flip.

My ghetto spring pack.

It's also worth noting that the forward hangar on my truck was nothing like the RC one. No point in even sending the pattern if someone is asking about it, not a single one of the holes lined up."
"Grabbed some pics of where the front hangars ended up.
You can see I just had to buzz the very edge of the crossmember there, I took a little bite out of the rivet head itself to scoot it back a hair more but it probably wasn't necessary.


Here you can see how I hung the parking brake cable bracket. I plan to drill some offset holes in it and just hang it right back where it was. My truck doesn't actually have an e-brake, bit that doesn't mean I want those things hanging all over the place. I didn't use the lower bolts on the hangars, but there's nothing stopping them from being used. I was just tired of drilling 1/2" holes.
