I would like to prepare a car to compete in a concours class. I have a '70 Mach1. Like probably most in the country, I do not have the factory wheel and tire combination on my car. It would have had 14"X7" black steel wheels with the sport wheel covers, or whatever their name is. I know back in the 70's those wheels were hard to come by. Are the wheels judged for originality and date codes? Thanks!
