I owned a 68 Plymouth Road Runner that came factory with chrome wheels but I believe we’re 14 inch though.I was thinking the wheels. Road wheels are certainly an option, code W23, but only as a 14" version with a trim ring. These are 15" with the chromed rim. I think this wheel might have been available on Fords but never a mopar. Definitely not a Challenger wheel. But they look great on the car.
