Look at a site for Tray Walden at Streetshopinc.com. Tray builds replacement Corvette frames and he narrow's C4 rearends daily. He might be able to help you. The biggest issue you will have will be the rear spring IF you decide to continue to use the rear leaf spring. Tray uses coilovers. I know that Wayne Due recommends the 84-87 C4 rearend as it is 1 1/2 inch narrower than the 89-96 rearend. Tray perfers the 89-96 reared as they have better brakes and are more available. Dana 44 Corvette C4 rearends bring $2,000-$2,500 where a Dana 36 runs about $750. Tray's unique concept is to install a new frame with late model Corvette suspension under early cars with no cutting of the body ulike all the other builders that require body modification. The reason all the others require body modification is that they do not narrow the rearend.
