ok so I've been doing some research and have came to the conclusion that Kaaz made the front/center lsd's for TRD. Here is some pictures of the TRD diffs taken apart:
Center lsd on the right. Center Viscous Coupling unit (aka vc) replaced with clutch pack front lsd on the left:
front diff looking at where the shafts that connect everything. Outer/Biggest diameter shaft transfers power from the center diff to the rear diff via transfer gears. The middle shaft takes power from the center diff lsd to the front diff lsd. And the inner/smallest shaft gives power out to the front left wheel from the front lsd:
vc carrier which is now the front diff carrier apart showing front diff housing:
front diff housing opened up showing discs and 4 spider, lower left in 2nd pic and middle of 3rd:
center diff opened up showing discs:
4 spider center diff:
Everything laid out. You can see there is like a bearing for the spider gears of the center diff to rotate, on the right shaft of the 3 in the first picture
So as you can see you would never be able to buy just a front or center lsd from TRD. They were all sold as one unit part#41035-ST010 for a price of 370,000 yen. Which would equal $4,655 right now. And this has been discontinued for years so the price may of even been higher now if it was still available.
Now look at these discs from the trd lsd's:
this was from a honda guy comparing lsd's.
Kaaz disc on the left next to a Os Giken disc on the right
So I think Kaaz was the developer and producer of the TRD GT-4 front and center LSD's
