Can you identify this transmission?

It came off a 1971 duster w/ 318 engine. I don't have full pics but if it helps, it states 962-10 on the bellhousing.

Top digits on tailhousing reads 0511, below it reads
3681600

View from front of trans to pan

this is the best that I can do(iPhone camera sucks) hopefully someone can identify this trans.

904, all you have to do is look at the pan. 727 has a bulge on the front passenger side.
