Default GRMN parts numbers? (Mark X GRMN rear diff torsen)

I've been looking for a parts list for the Mark X GRMN.

So far, I've found the following:

Per this: https://toyotagazooracing.com/pages/...x/specs/specs/
Base vehicle code is GRX133-VMWBMT
Model code for the GRMN is GRX133-VMWBMT
Final drive for the GRMN is supposedly 3.615

I can't seem to find the GRMN model code anywhere.
I'm very interested in the part number for its diff assembly, more specifically the "case sub-assy, rear differential". Supposedly it's a torsen, yet the 3.615 final drive only appears in cars that have never ever had an OEM torsen option. (2nd gen IS350, 3rd gen GS350 & 450h, so on).

Many thanks if anybody can find this info! Not too sure if this is the right section, but given that it has potential implications for a lot of older vehicles...
