Most if not all the people who are telling you to part it...want parts from it.lol
FIX IT, TAKE YOUR TIME...NO HURRY.
Its just sheet metal , patch weld or flange it, fill it...no one cares if you use expensive repop panels and they shouldnt.
Just maybe buy the repop rails and then just grab a sheet or 2 to do all the rocker panels, lower fenders,1/4. I've seen worse get brought back in about yr by guys with no money , just brains and a welder with some paint skills.
I have looked into trunks and seen plain sheet patched in, painted and nice...and said to myself.."this car could have been junk, if some Galen goobier had decided rerop parts or scrap...this car would be a memory.
Save it!
