I did question a NSRA Rep about a "Mopar in Mopar" as they have a "Chevy in Chevy" and a "Ford in Ford" display. Was told that because it has been done this way for so many years that it will not change.
The NSRA Rep is a true Mopar guy too.

Maybe if Ma Mopar was the " Mopar Country" sponsor it might be different. Yes, probably 60% of cars in Mopar country are powered by others or
other body with Mopar drivetrain.
