What diff fits on a E36?

The US E36 (M3 and 325/328) differential uses a 180mm ring gear. The Euro M3 used a 210mm ring gear which has been proven to be stronger than the standard US M3 differential. This bracket makes it possible to bolt in a differential from the E32 750i (or E34 M5) which has a 210mm ring gear.
