Everet - Yes, I did buy the Sportage from Didi. He finished his grad program in June and should be back in Brazil now. But he really loved that Sporty, which made me all the more comfortable buying it from him. And he did have good things to say about you and the lift kit.

And now back to the OBX diff...
I did some quick measuring and here are some dimensions that should clear things up regarding the rear carrier, I hope:

- 10 holes on the ring mount, hole-to-hole on the outside edges measures 5.7" and 4.9" between the inside edges (approximate for both). So that should be about 5.3" center-to-center.

- The bearing mounts are 1.575" in diameter.

- The ring mount is 6.06" in diameter.

- And the length of the diff, bearing-end to bearing-end (in-line with the axles) is 6".


I am 95% sure the diff will fit both front and rear. From what I've gathered between this forum and others, the hole pattern should be the same for both the 7" and 7.5" ring gears. I think the difference is in the rings, with the 7.5" being a bit beefier with the extra 1/2" of diameter. And that would jive with the Mazda-boys not being able to mount the 7.5" ring in their diff assemblies, because their housings lack the space for the larger gear & matching pinion, even though the diffs are the same... I think. My biggest concern is with the ABS-sensing ring mounting. I haven't come across any mention of that being an issue/non-issue with the OBX diff for the Miata. So I'm not sure what to expect there.

Looking forward to hearing how the numbers compare... <img src="/forums/images/graemlins/scared.gif" alt="" />
