Probably not enough people consider the body itself ... my first inclination would be to just bolt it down and go from there, but there is a LOT of wiggle room in the body to frame connections.

Assembly manual calls for shims as necessary. My 55 Bel Air had a shim stack about 3/8" at a couple of locations. There were also some alignment holes in the front foot wells to the frame that really helped. The factory workers would use a spud wrench to locate the body on the frame and then tighten down all the mounts. I didnt see any alignment holes in my 68 but the floors were replaced so maybe the reproduction pans didnt have the holes?
On a 55 Chevy....the front clip was set in place as a complete assembled unit. Our 68 GTOs were built up. Core support first, then the fenders with the inner fenders attached and so on.
