4 speed identification?

Looks like an A833 to me
the A-body kind, with a 1x23spline input
I think 3034 is Nov 17/1970, making it a 1971 model[/QUOT

0B, so it is from a 1970 model built at Hamtramck.

A 1970 Duster in this particular case.
Thanks a lot guys. I'm glad it's not some weird year not very good tranny. Thanks again.
