Do you have an e36 or e30? I have an e30 318 diff laying around takeing up space it only have 70000 on it when i took it out for a medium case lsd. I am fare away from you but if you get desprate let me know. If you have trouble finding a small case diff you can but the medium case in which is alot easier to find for cheap. You just have to ajust the drive shaft forward and everything else bolts right up.
