I believe 6000 were v8 cars less than half were HO 273 4-barrel cars with the Charger 273 V8. The other V8 cars were the 180hp 2-bbl cars red air cleaner and valve covers. Chargers were yellow with black or gold interior (gold never saw one) some had the black top. I read most were not exactly a GT but 270 cars with the trim down the side of the car.. and there are a few convertibles. All built at the LA plant from October 1964 to March 1965. The hard top had flex issues so the post top was the idea and later used as the D-Dart 273 in 1966. The Charger was the 273, 4-speed and had a 8.75 rear end. The Go-Go Dart was a 904 and 7.25 rear end. There are rumors of /6 Go-Go Darts.
The Charger 273 motor was in all the Chargers because it was the 4-bbl and came with black finned valve covers and Chrome air cleaner.
Kits were put in all colors.. they were added to the GT cars and the Auto 904 cars were called Go-Go Darts.
