Dave, It's an open drive.
I think were thinking of two different things??? You only need to remove the retainer to press the old seal out from the backside.
The seal for the yoke is pressed into the rear housing/retainer, than the yoke with speedometer drive gear slides onto the output shaft of the tranny, one bolt and thick washer and your done.
Marv, maybe you should pull the back of the tranny off to see what's going on. I can't remember that needing to be done, but who knows?
