I'm unsure. The car was made from 2 GTX and at least one sports satellite parts that I can figure. Thus not close to numbers matching. But is period correct. Who did this was 25+ years ago. And passed away years ago. Car sat 15+ years in a Chevy lover's pull barn. He attempted to sell me a '71 Nova for near same price. My answer was consistent. "Just the facts on the Plymouth sir." I drove the car home 250 mi. Ran like a champ. (Poor chase truck trying to keep up. Lol) That was 4 years ago of this "Just another Plymouth tale."
