rear lower corner panels

On my 48 coupe that I'm still dismantling, I've discovered that the left lower corner panel is crushed. Is there a source for new or rebuilt ones? I had to get new impact bits to finish removing the Phillip screws screws,being that I've already one of my smallest bits while removing these old screws. I'm looking for new ones if that is even possible. Will the rear corners off of a sedan work on the rear corners of a Club Coupe?
