Not a A-body,,,but an extremely rare mopar (* forest find !!!)

Congrats Valerian on your find, looks like you have the talent to ressucitate this
RoadRunner/GTX..........

If I may, I'll tell you a little story about another RR/GTX.......in the early nineties I bought a 1974 RR/GTX from a wrecking yard near St-Tite, Québec for 125$. A 318 ci was in the car but of course I knew it came with a 440 from the factory.

A Mopar magazine run an article from a guy in Livermore, California who owned a 1974 RR/GTX and claim to have documentation that only 79 RR/GTX were built in 1974. He start a registry for these 1974 RR/GTX and will send documentation to the member of the registry only. Of course, I send him copy of the broadcast sheet and the data plate BUT never heard of the guy anymore. It was before Internet and little I can do.

I later sold the car but keep the broadcast sheet and the data plate, NO interest for the buyer!!!!
