And the 1965 Dart Charger was NOT a factory offering, but a California dealer inspired package. The Charger nameplates appear to be something designed by someone not connected with auto styling. Look more like a paperweight than nameplate. Some models also had stripes on the hood and trunk. All other equipment on the car was straight off the options list, including the 273-cid V8.
Chrysler had problems fitting the poly 318 in the engine bay on the A body engine bay. There was absolutely no room for a B block engine in there.
Also do not know where the 180 number came from. As it was a dealer package there was no separate sales code for it The only thing I have heard about production is that they ordered more nameplates than they had car orders.
