Anyone have a tail shaft for 3 speed manual B BODY.

Have a guy looking for a tail shaft housing and front bearing retainer (at least that is what I think it is called ) for a 1973 roadrunner

Are the 4 speed and 3 speed tail shaft housing the same?

Ok the bearing retainer on the input also let's the throw out bearing ride on it? Is this correct? Hell been too many years since I was in auto mechanics school

This guy has been looking for over a month and cannot find one. It is a 340 3 speed manual ONE OWNER car.

Any help would be appreciated.
