a833 B body/E body to A body conversion

hey guys, I'm 20 and my 1969 Barracuda is my first classic car, it is an automatic that I want to convert to a manual. My question is regarding converting a B body/E body a833 to an A body, I am lucky enough to have a father who has been accumulating parts for his whole life mostly for B bodies though. He has a few a833s for B and E bodies he is willing to let me use so I'm wondering what I would need to get to "convert" them I'm assuming I'll need a new tail housing, but I'm not sure what else. Also if anyone has any of the parts I need and my father doesn't already have them, and you are willing to sell them please let me know.
