Too wide and 93 and older are 4 lug (can convert though)
I am not sure of exact measurements without looking them up, but an A-Body is 57 1/8", an Exploder rear is 59 1/2, but shortened to 56 3/4" with two short side axles. Shortening one side does center the pinion, but no clearance issues with that. A Rustang rear is centered pinion already and uses 2 "long side" axles.
