700R4 reliability questions...

[bnoon]

O.K., I just found out that my spare trans has a cracked 4 planet carrier... no problem, right? Well, there's a small chunk missing and I don't want to use this trans if I don't have to... Everything looks a bit more worn than I would like, even for a rebuilder core... everything feels tainted. So I went to ask about the second trans that's in a friend's garage... 4x4 output shaft and tail housing... I remembered the tailshaft, but forgot about what a pain that output shaft is! ARRRG! No biggie if I wanted to grab the longer output shaft from the "tainted" trans, but I'd rather have new. The other tail housing is fine as long as I use a new seal, so...

Do you happen to know the part number for the new correct length output shaft? Couldn't find one on the bay or through GMPartsdirect (yet)...
