Sorry for the delay but iam very busy when in the garage. The ? mark ment I am unsure the year gm stopped making the style suspension I used. I know the one I used was from a 85 1/2 ton. There is some fab work involved but the main cross member is pretty much a bolt in deal. I made my own upper shock mounting brackets. I used the stock 1/2 ton monroe shocks but moved the mount up on the frame rail. There less money then those dropped shocks for the low budget guys. I also lowered my truck 4 inches in the back and used the same front shock for an 85 1/2 ton on the rear. you can use the stock hardware that comes with the shock you just have to drill a new mounting hole. Just an FYI on the shock thing.
