Part out or sell as project?
my best friend had a beautiful 62 300. It was scary fast for a big car, 426 wedge w/dual quads, cast iron headers. It needed some relatively minor rust repair, but my buddy wanted to do a primo resto so he sent it to some "hotshot" body and paint guy. That was over 20 yrs ago. The guy did a good job taking it apart, and prepping it for paint, but it has been stalled for the last 15 years. In the meantime, he''s damaged the interior by leaving it sit out in the weather. What was once a very nice car, is now a primered bare body, with everything else in boxes (maybe!). Get it out of there, and get it to someone who is capable of following thru with a project. It may not be top tier, but at least it will be done, and you can enjoy it.
