Well, the local 4x4 shop can't find an Eaton LSD. So getting one through them won't happen. On another note, I have a CAD program and made a drawing of a "hybrid" OBX case (ring gear side only) with the Kia-specs for the ring gear mount. Here's a comparison of the stock OBX case for the Miata and my red-headed-step-design. Sadly, I've been calling around to local machine shops all morning to get a quote, but can't find a shop that will even look at the job because:

A) "We don't do small-volume"

or

B) "We won't make automotive parts"

So, if anyone knows of a machinist that can/will do the job for a fair price, let me know. And now for the pics (3D renderings)...
