Thanks. It is apparent that the lower corners of the rear pillars are "a problem" under the vinyl. I bet that is where the trunk was leaking, and it may have migrated to the rear window channel. So this is not exactly a walk in the park. And the trunk floor is for all practical purposes "toast."
So it's not a walk in the park. But the rest of it appears SOLID..Looking under, the main floor pan, rockers, etc are pretty much rust free. And it is STRAIGHT. Bumpers show a little rust but "driveable." Some of it may polish out of the bumpers. No dents or bends in the bumpers
Now,................if I can just live through to spring LOL
