Wayne, someone needs to fix this before we end up with cars that have panels welded on top of panels!! Although, judging from the double door skins on my friend '57 356, someone has already tried it out.
"When mother nature and the elements have taken a toll on the sheet metal of your car, then replace it with direct replacement panels from Pelican Parts.
Designed to be directly welded in place over the older, rusted out panels."
