1965 dart sport question for a friend

[Demonizer71]

He has a 273 commando V8 and is wondering which auto transmission it would have come with a 727 or 904, anyone know for sure, I'm not up on much after 1968 The fender tags dont tell you much.

Thanks in advance

Only the 904, the bell housing area on the car is smaller up untill 66.
