WTT: My 4.10lsd for your 3.73 or lower

I know it's a long shot but you never know...

My 4.10lsd from my 91 318is for your 3.73lsd or something close.

NE area would be great...

The 3.73 is a large case diff. The 318is is a small case diff.
The 325is automatic also came in a 4.10 but in a large case.
Unless your 318is was swapped out. Most 318is did not come with an LSD. Mine didn't.
But I swappedo ne in from a automatic 325is. I had to swap the flanges.

To my knowledge, the 3.73 came in a med case and they are perfectly interchangable with my small case 4.10.

E30's only came with small and medium case diffs, I changed my small 3.93 open for a med 3.73 out of a 325is with zero issues.

Thanks for the confirmation, that is what I thought.
