The issue is; I purchased a new chrome rear bumper and new rear brackets. Double checked and triple checked the part numbers. The bumper was from LMC and the proper rear brackets were from Summit Racing. The brackets when bolted to the frame in the correct orientation do not remotely come close to matching the holes in the bumper. We’re talking several inches difference. Btw, I also purchased a new front bumper from LMC and it fits perfectly.
Just trying to make sure someone hasn’t done some sort of frame swap in the past.
