I don't have pictures, but the rear bumper on our '84 was in bad shape. It came with a pretty good dent in it. I nearly finished it off by catching one of those posts that protect the pumps at a gas station, bending one end of the bumper out to a 90 degree angle and tearing the horizontal sections where the mounting bolt holes are located.
A nephew who was in welding school took it on as project and tells me it is all good now. I haven't seen it yet but was glad to pay him a hundred bucks for his effort. No idea how to find a replacement.
