For rust repair replacement section for a HG Brougham RH quarter, which model is the closet in fit? If it is just a case of being longer, but the same rear section, I may get away with using a trimmed one, or do I need two of another model spliced together, or as a final option do I just make one up myself? I fabricate panels for a job, but it is not worth my while making panels that are already pressed.
