I am in the process of putting a 58 fleet on a 91 s-10 frame and no kit, I built everything that I needed from scratch, and sold the motor mounts I had purchased from Jtr. I needed the 350 higher and back farther than they would allow, moved the rear end back 6 1/2 inches from info I dug up out of the H.A.M.B. form at the jalopyjournal.com site Good Luck with your swap
