W163 Differential Rebuild Kit

Mercedes » M-Class » 1998-2005
Problem Description

Greetings!  I just saw a post in the latest MB Medic newsletter that has me wanting to try a project:

http://www.mercedesmedic.com/rebuilding-mercedes-front-diff…

This article and video are about the W164 chassis and I have a W163.  Does anyone know where I could find a kit (or do you have the part numbers/bearing manufacturer part #) that I could use on my ML320?  Trying to get all the drivetrain and suspension brought up to scratch on her and this seems like a sensible project at nearly 300K miles.

Thanks for any help you can provide.
