Can't run an overdrive...wasn't offered on Plymouths in 1950.
Someone asked about the cooling system...rules say that cooling system must be stock, but water pump impellers may be altered.
Gearing options are 3.73, 3.90, and 4.1...there may have been a heavy-duty option for 4.56, but I'm still trying to confirm that.
Wheels & tires may be of any size...period photos show the use of 670 and 710x15 tires, slightly larger than the 6.40's that came stock on the Deluxe models.
Body must remain stock, complete with hood, bumpers, doors, fenders, etc. Rear seat cushion is to be removed. Photographic evidence suggests that many cars had stripped out door panels, headliners & floor mats. Others had complete interiors and were actually registered and driven from race to race.
