I had a very nice and rust-free '70 only 'Cuda door shipped in from California and the gorillas at Greyhound apparently tossed it around for fun. Both ends have a fair amount of damage. I was able to hammer/dolly the rear edge back to shape and it is almost perfect, however, the front edge sort of "crumpled" in on itself and rippled in. What is the proper way to fix this type of damage? I think if there was a way to pull it, most of the damage may pull back in shape, but I have no idea how I would go about doing so?
