I’ve been diggin’ on old photos of this car for years.
Was it a GTX or a RO23 super stock Belvedere II? Did it have a fender tag? What was the original color? How did they decide on the paint scheme. Tell us more.
In the last photo it looks like a bench seat and GTX never had that. It does have the GTX rocker trim and not the upper body trim of the Belvedere II.
