I'm Heartbroken. Time to face reality that my Cuda is a parts car.

You, yourself said "find a cheap more door". That's how I saved a 68 vert for a friend/customer. When the serious rust was out, it was literally gutted like a fish. Firewall back to tail panel, rocker to rocker. Can be done. Patience, don't think it has to be done tomorrow. Vigilance, strike when the iron is hot on good deals for parts.
