Differentials

Hi all,
I have a 1985 E30 323i.
I'm looking for a LSD. Did any E30's come from the factory with a LSD, other than the M3's?? If so what vehicle & ratio are they??
Does a LSD from a E36 bolt in??
Thanks for your help.

318is had LSD, but they are small case diffs and cant take much high performance driving. i know there are some others, but i cant think of them right now. M3's had big case diffs which could withstand a lot more beating.
