Default Differential parts - one 7" open diff, one rear aluminum housing

Fucked your **** up recently? I've got the parts you need to fix it all up.

One open diff from a '94 Miata. No front pumpkin, no rear housing. Just the diff itself. $50 shipped.

One rear aluminum housing from an '86 Rx7. Throw some Miata bushings in this and it will bolt right up to everything else. These are HARD to find without buying an entire diff. If you've cracked or broken yours, snag this one. $75+ship to the lower 48.

Rafa, I think you might need to source some halfshafts. Not totally sure. I have a spare set of Miata stubshafts I can throw into the deal.

Urban, you busted the front case too?

Its been a LONG time since I've read all of the parts interchanges for the rearend so forgive my ignorance. Would the open diff fit in the RX-7 housing?

2. 86-88 RX7 assembly conversion:

Parts:
86-88 RX7 NON-TURBO differential assembly
94-95 Miata stub shafts or RX7 stub shafts and 94-95 Miata half-shafts
or 96-05 Miata axles (no stubs needed)
RX7 Circlips (fit onto the end of the stubs/axles, miata clips will not fit)
94-05 Miata driveshaft
Miata Ring and Pinion
Miata Pinion housing (pumpkin) (find at RX7 performance shops)
Miata Diff. Bushings

So if I bought what you have all I would need would be:
94-95 Miata half-shafts
RX7 Circlips
94-05 Miata driveshaft
Miata Ring and Pinion
Miata Pinion housing
Miata Diff. Bushings

Am I reading that right?

yup. Interesting that you need Rx7 circlips; I'll have to look at that when I get home this weekend. The diff shop installed mine with the Miata clips, so I wonder if it went in OK. I have a set of Rx7 clips chilling at home so the swap will be easy.
