I have been asking everyone this question for sometime, including our friends in Germany...
The rear gear can be programed with the STAR DAS system. We did this with my car. Where to find the gear? If they use the same rear end a good place to look is smaller engined cars such as 230's four bangers and maybe the the smaller V6 240's.
Just checked and 230's seem to use the 3.27 but C240's use 3.46 !!
Hear is on on Ebay. Ignore the picture as it is just a file photo and not of the actual diff.
