1965 Dodge Dart Charger
Not to throw cold water on your excellent efforts with your potato stamps, but isn't a mat from August a little off for a January built car?
Actually, you do get a bit of a pass as far as dates go for an L.A. built car. Since there would have been very few suppliers in the immediate area, I'm thinking much of what the plant assembled into cars was shipped a considerable distance. Under FWIW, I have a '79 Aspen wagon that was built at Hamtramck with an engine built at the Windsor Engine Plant. Both have the same build date and the engine is original to the car.
