I have an 04 Mazdaspeed with a 4.1 Torsen II.

I want to change the ring and pinion to a 3.63 .

I went on the search sites, like car-part.com and others for a Mazda 626 Diff from (80-82). No dice.. or about the same as new gears.. (550)

I saw this chart.. what other cars can I get the ring and pinion out of that are compatible?
Solomiata : Transmission : Ring and pinion tooth counts

Getting close to 3.63 (like 3.7, 3.727) would be fine too

Thanks
Jeff
