Long story short,
I sold my BMW to a guy in L.A. and the input shaft bearing on my diff went out on the drive down here. It's a 85 635csi with a 3.46 LSD
Went to the wreckers and got a open 3.45 off what he said was a 325 (a LSD 3.73 was $100 more), although when I got home, I see the diff cover has a completely different rear cover and housing. The old diff cover will not line up, although the output shafts do.
I'm suspecting it's out of a E36 based on some basic research of part numbers on Pelican. Anyone know what this is off of? Diff tag reads 345 N5701. The cover reads 1214110
I've included a pic of the diff along with my original cover
I got to have this thing changed out by Monday
Guess I'm back there tommorow with more money, grrrr.....
