Not a A-body,,,but an extremely rare mopar (* forest find !!!)
I owned a 74 RR for a bit (traded the car for another Mopar) back in 2001/2002. Did not know about the GTX package and this one does not seem to have it, was a cool car in Yellow Blaze, black leather and a 440. Never drove it.
Good luck with the RR/GTX resto!
