Randy, I took the M3 diff cover off the coupe and mounted the new finned cover on. I used stainless allen head bolts.

We had a 2003 Jag in the garage this week for rear brake problems. I learned all about the automatic electric parking brake which is also on some 7 series. On the diff they use an alum cover with 2 bolts going to the frame.

I posted pics of my covers and the Jags at http:www.msnusers.com/arizonaclan
