Would used 67 coupe doors with no rust through, no body damage, and all internals working including glass be worth $450 each and a 6 hr. drive? Before answering, I have visited every used Mustang vendor in my state and private parties to come away with nothing useable.....always dents, non-working parts, rust, etc...
I think you answered your own question, so long as they live up to the description you've been given.
Well the oh so questionable fit/finish quality of the repo doors would make me want the OEM Ford doors.
