I was thinking that as the collar won't slip off the torque tube and I have to cut the gasket to go around the TT then I would have to cut the steel washer - the rear most one. The one at the front end of the collar would not need to come off so I would leave it intact. And I do not know about the "nut". Maybe I am missing something here. Might see it differently once I have it apart.
I went through my gasket collection and found the Fel-Pro "Universal Joint Set" . Their number is ES72843. The kit consists 4 retainer shims, the rubber collars/packing for the join between the ball housing and the rear of the transmission and the threaded collar.
