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

Sweet find! never heard of these so I pulled out my books.
Galen Govier book, looks like they made 11,555 of the Road Runners.
386 Road Runner GTX 440-4 were made and shipped to the USA. I don't have a number of CDN cars.

As for the 2014 price guide, 1974 Plymouth Road Runner 2dr CPE in #1 condition is $14,600.00. Add 25% for a GTX. she'll be worth $18,500.00 if you can get it there.

Not sure which code denotes CDN car, but I'm sure it is which would make it even rarer. hopefully you find the broadcast sheet!!!!

:burnout:

C on the fender tag means Canadian.
