This is the medium size case with a 188 mm ring gear, and to make it fit your car, you just have to swap the rear cover and perhaps the pop-in drive flanges. Does not come with a rear cover. You will install your E30, E24, E28 or E23 cover. Condition: I have cleaned this unit to look as it does in the photos.
The outside of the case has a fair amount of rust, but the inside is terrific. The ring gear and spool are quite clean and the unit did not leak.
The pinion spins very smoothly. This is the real deal - no gunk or residues, suggesting this is a well cared for diff, with the oil changed according to BMW recommendations. Be assured, this diff is in great shape and will not whine! It takes experience to evaluate these units, so you can trust my description.Thanks for checking this out, and good luck.
