just use the miata clips, both me and Y8tes have used em no problem, and they lock in pretty good. If i need to pop em out, i got the prybar for the job so im not worried about that.

Just for future reference in case someone is searching through these old threads...

It's been confirmed that the 84-85 diffs cannot be made to work without leaking.

86-88 diffs are the only ones that will work correctly.

I searched through these threads over and over when I was starting my RX7 LSD project and couldn't find any info about 84-85 diffs leaking so I spent months trying to make an 85 work. Don't be like me! Start with an 86-88 and save yourself the hassle!

How common are the circlips? Will most auto part stores carry them? Will dealerships carry them?

I have a 88 RX7 Clutch Type Diff, I am planning on using the axles from my 97', front pinion housing from my 97', Polyurethane Miata Diff Bushings , RX7 Rear Housing, RX7 Circlips and seals. Does this sound correct?

necrothread:
So can you hammer in 1-piece axles with the miata clips or do I need to put RX7 style clips on there? I was under the impression that I had to get a groove machined inside the trunion shafts.

Also, where can I get a new clutch-pack?

pick the circlip per the axle type. the grooves in the axles are different from the rx7 stubs and the miata stubs/axles. Mazdacomp has discs.

so do I need to get a groove cut in the trunions or not? Some say I do, some don't.

what year diff is it?

The problem some, myself included, were that the late model 84-85 units had solid axles. so while everything dropped in place, there were no groves on the 'trunnions' for the circlips to expand into:

It's just splined.

If you source a 86-87 unit, there are grooves cut into the end so once you push the axle far enough, the circlip will grab against something:

I have the early rear end. What do I need to do...take the splined trunions out and get the splines cut down? Any idea how deep I need to cut?

Thanks.
