FS: 3.64 open e30 sm-case diff
 

Selling the small case 3.64 open out of my e30. Has approx 250k miles on in, no noises or excessive play. M42's don't put a lot of stress on a diff. I think you might need to swap the axle flanges to fit a ti but I'm not sure.
I have fedex acct so it won't be too bad. Pics on request, can pop the cover and take pic inside also if you like.

$100+ shipping Obo.
