rockauto has everything your probably going to need to fix that issue. im not familiar enough to know exactly what your after or if the parts your asking for are correct. anyway rockauto has an acdelco output shaft sleeve listed. there is no listing for an oring for that and im definitely not flipping through gm part direct trying to find a part you could also search for.
acdelco output sleeve
08654063
with or without the 0 in the front.

I was just really verifying that this ws the right O-ring for the sleeve

same sleeve p/n i found. gm parts website for parts breakdown i think is a terrible setup website so still unsure about that oring. it calls it the rear output shaft seal the output shaft seal i found is not an oring.
