The car had the incorrect rear end in it that was only held in with two bolts. It was wedged in and was to wide. Again I had a friend who had a 1968 f-body 12 bolt rearend that I bought from him and installed. I had to buy perches,axles, and bearings. 12 bolt rearend. New axles, installing studs. Drilled everything out for one size larger u-bolts. Installed new bearings and seals.
