-The 3.25 LSD came out of a 1984 633CSI with ~190k miles I had to clean and repaint it (it was down to bare metal) so it doesn't actually have the 'S' marking on it. In the pictures it has E24 flanges and cover, but I have a set of E30 flanges and cover that I can put on. If not all that needs to be done is swap out the rear cover and flanges out of your 3 series and it should bolt on! This ratio is also great for 24v swaps.
-The 3.91 LSD came out of a 1992 325i with ~135k miles. Medium case differential, comes with E36 flanges and cover. Does not fit on an e30. Only thing it needs is a new gasket, though I just ordered one for it.
