Like the title says- I have a clean 3.15 LSD with 4 bolt input flange from a '94 325i w/~120k miles. No noise or other issues, works perfectly.

$400 picked up near Raleigh NC or will ship at buyer's expense. Estimate shipping from ~$60-80 depending on your location.

Good Luck, I thought that was the going rate for a clean 3.23 - I would be interested at the usual 250 or so.
