The issue is not getting the gears, its finding someone who is willing to install them properly. The M diffy in the E9X M3 is a little finicky when it comes to tolerances in the diff.

Here's diffsonline.com page that has the ring and pinion.

You can buy a re-manufactured diff from bimmerworld.com. Here is the webpage..
