I was talking to you earlier. Might be interested in a 3.15 after all... I have a 3.38 that is in need of rebuild. The only thing I would honestly guess to be good in this diff are the gears, so it needs a full rebuild. You can read about the problems with it here: http://forums.bimmerforums.com/forum/showthread.php?t=925787

So since I can't afford to rebuild it, I'm looking for one of the more available diffs. Send me a PM and let me know if you're interested in a trade + cash from me.

whats the mileage?
