Well, for those interested. .....here's my (old) BMW rear end.
391 ration with 25% LSD.
Broke it after driving 1500km to the Australian Cobra Nats. Turned 8 laps before crunck! Turned a tooth. Make sure when you do your diffs that you DON'T re-use torque bolts and make sure you set the diff lap low on the teeth.
Car is now running BMW Motorsport shot/peened crown wheel and pinion
