Got most the stuff out of the way and started mocking up the 4 link and cantilever kit from KP. Talked to them before ordering and i knew we would be close to fitting, but not a direct bolt-on. What I've found out:

1. The leaf springs are shorter on the suburban, so the front mounts need to be moved up on the frame.
2. the front brackets work better if you flip them over and switch sides..driver to pass and pass to driver. It provides better clearance and keeps the bracket more centered in the frame.
3. the cantilever kit will have 2 bolts that line and the rest need to be drilled.

We're going make 6"x14"x1/4" plate and weld the kp brackets to it. then we will drill and bolt the plate to the frame. Since the pickup brackets don't line up for a suburban and redrilling holes would be putting a lot of force in spot we figured our plate would be much stronger.

For the cantilever in the back we're planning to put a plate on the inside of the frame rails with the nuts welded to it. This way running the bolts in will be much easier since the gas tank in they way and some of the rear frame is boxed.

We will also make probably be making a custom bracket for the panhard bar, too. I will take better pictures once we pull the frame from the suburban.

Now this is a lot work for a bolt-on kit, but keep in mind the kit we bought was intended for completely different truck. I bought this setup knowing i would have to workout some kinks, but i also knew it would strong, reliable and very close to what i needed. A bolt-on kit is only putting wholes in the frame, so the truck could be returned to stock and/or upgraded rather easily.
