Jason posted the xB part numbers needed:

If anyone is interested in the parts needed to do the xB final drive (4.312) swap:

33321-52110, output shaft
41221-52270, ring gear
90105-11040, ring gear bolts (8)

Is there a difference between the old/new parts? Some sites don't have the new numbers, so here's the old ones:

33321-17011, output shaft
51221-12340, ring gear
90105-11040, ring gear bolts (8) (no change)

At this point, I'm going to either make a new thread or keep chasing these ideas on the xB final drive swap thread
