I have a LSD Carrier for an E30. I was truing to develop something for a 2002 but the carrier is too large to use in the smaller cases. Anyway the carrier is complete with the output flanges. If you have a open diff and would like to go LSD this is the way to do it. Simply remove the open carrier remove the ring gear and transfer it to the LSD carrier. Put the ring gear and LSD carrier back into the original case and you've got a LSD. $200 USD shipping from East Tennessee 37932.
