3/S rear differential discussion, the "H", "G", and the "J" specs, is it JDM, US, UK?

which would make the only "oddball" of the group the USDM 6-speed rear; which is the same part as the atx rear.

Don't know if you ever got your answer but I can get you new OEM ones . . . for a price:

I can deliver in about 3 weeks from order with payment:

MR179436 (entire Ralliart 2ws rear diff) - $4394.00*.

MR179437 (entire Ralliart 4ws rear diff) - $4394.00*.

MR196307 (just the Ralliart rear diff pineapple, same for both 2ws &
4ws) - $3412.00*.

*Does not include shipping which I estimate at $200, and requires your 6 speed or auto 3000GT or Stealth transmission to be upgraded to JDM GTO gearing (JDM 6 speed parts are generally available used at reasonable prices, may not be an option for autos. US 5 speeds (I have heard) and gray market RHD JDM GTOs in Canada already have the right gearing).
