73 dart build date

Model year production starts in the previous year, late Summer to early Fall. It ends around late Spring to Summer. I have a 1970 Challenger door stating it was built in Sept. or Oct. 1969 (forgot the exact date). My 2004 Dodge Ram 3500 was built in July of 2004, among the last ones from that model year.

Fnasausage's car is a '73 and OwdKasd's car is a '74.
