Default Mm6 manual trans question

Can anyone help with a tranny question? I am in the process of installing a new differential with 3:90gears. So, before i put things back together, i am thinking i should replace the tranny output shaft seal and o ring on the output flange. Here in lies the problem. The chevy dealer cant seem to find the correct part numbers for these two parts. I have the shop manual and i cant find a breakdown of the of the output shaft. Can anyone shed some light on this? It is a 2004, 6 speed.

Thanks
Mark
