Welcome to the BBS Tom. Is the car black? There was a black 74 ragtop FS a couple years ago by a guy named Alex Claytor, I think he was from Bakersfield or somewhere near there.
The ragtop looks ultra cool and is definitely a show stopper, they are all custom. Wilco converted them or sold the kit. I would look more at the overall condition of the car as more important the ragtop issue.
Hey buy that car and join us for the West Coast Classic in June! Click the link in my signature!
