S15 differential woes. need part numbers for rebuilding purposes

[nextproject]

So, courtesy nissan has apparently lost access to the Japanese FAST catalogs.

First off, is the S15 differential housing itself different from the S14 ABS housing? if it is NOT then i should be able to just order the crush sleeve, seal, and pinion bearing from nissan for that application. Otherwise i'll need to get in touch with someone with the Japanese FAST catalog in order to get part numbers necessary to swap my 3.69 ring and pinion into the S15 diff someone sold me that has a 4.10 in it.

I have over a thousand dollars worth of diff parts because alot of people cannot tell me what will work and what will not work.

I'll tell you this, an S15 3.69 ring and pinion will NOT work in a J30 housing. I figured since both diffs were ABS and R200s that it'd be POSSIBLE, but after disassembly, the pinion shafts are different as well as the bearings. So that was a no-go.
