67 Barracuda
What state?
On any "early" A body, I like to stick my arm up as far as I can in the passenger's vent, to feel the lip of the opening.
If it's rusted there, it's a deal killer. Most other stuff can be fixed.
I've been looking for a 68 FB for several years, and finding any for under 4K is difficult, let alone one with a good cowl.
