I have a 3.64 open rear end and a Euro 3.07 limited slip differential avalilable in Southern California. The 3.64 does not leak and has the hubs attached. It would be available for free for anyone who wants to pick it up. The Euro 3.07 is in same condition but does not have the differential oil cooler; that went on my E3 Alpina. Make Offer on the 3.07
