Bought this a while back to swap into my torsen diff and ended up not going through with it. Now that I've bough the Mfactory 3.33 unit, I have no use for it. This thread specifies that if you swap the pinion bearing over from the miata diff, everything bolts up as it should. I have personally measured the pinion against a 4.10 mx5 piece with a dial caliper and the length of the two are the same along with the diameter of the section where the main bearing sits. Asking $300 shipped for the set. Located near NYC for anyone who wants to pick up for a little better deal.
Still got it, it's from a late 80's car. Specific year I'm not sure. I'll be home after new years if you want it I'll be able to ship out then. Let me know
