It's about sources.

If I had a yard full of Mopars, what cars should I look in hoping to find a 4-speed overdrive tranny?

I think they started in 1975, but have no idea what all models they came in or what years following. My best bet might be Pull-A-Part, and they only list cars by name. No parts lists. So I need to be able to go online with a list of car names.

M-F-J bodies I believe are the best sources

Monaco, Fury and Jaguar, right?

Thanks

If going into a Mopar A-body then you need to start hunting down the following for "plug and play" versions:

1975-1976 A-body (Dart, Duster, Valiant)
1976-1979 F-body (Aspen, Volare)

Get the whole shebang...belllhousing to the driveshaft yoke...
