85 vette front suspension x member is exactly 1/2 inch narrower than the inside of a c cab frame. weld in 2 1/2" plates, kicked in 1/4" on each side, and bolt in the x member, Rack and pinion is also bolted to the vette x member. I have a buddy that we did that to back in 85, We also put the vette rear 3rd member in. Jim Turner Sep 2002 ====================
