I don't think one from a truck will work in an A body but I could be wrong
1975 was the year they were cast.
I gave one away
I have a A-Body OD 4 speed from a /6 Dart Sport. $50 plus shipping. I need to move some parts I know I'm not going to use. I prefer to let them go instead of scrapping. I have not used this trans. Spins freely though.
