I heard that GT Transmissions sells them, but I can't find any info on their site (not even sure I'm at the right sight). drivetrain.com sells the rebuild kit (http://www.drivetrain.com/nissanRS5F50Afwd5sp.html), but the last year listed is 1996, and they list different sizes for the differential bearing. Not sure which one to use, and I'm not sure how much I trust them to tell me.

I guess I could always go to my Nissan $tealership and pay through the nose; I was just curious where others were shopping.

 

Courtesy nissan probably have them or dave B the parts guy?
