Pro as in PRO STOCK and not the vernacular used for a certain bracket racing class. Yes, that's what Pro Stock cars
originally looked like and just how far removed from the original concept of this eliminator so-called 'Pro Stock' cars
of today are. I have to point that out for the younger crowd lest they think this Duster is just another garden-variety bracket car.

If you seen these cars back in the day like this (then) kid did, you'd know just how bad-ass and exciting they were to watch.
