Almost anything can be fabricated by hand. It's time consuming but a complex section can be rebuilt, piece by piece. All you need is some new metal, a cut-off wheel, snips, a MIG welder, project board for making patterns, and lots of patience. Metalman, how would you make a replacement panel that is not normally available with a repro panel? I've spent many hours rebuilding difficult areas like rotted out rear/front windshield openings but if you have a better way, I sure would like to know about it.
