I would have to argue that. I am VERY far from an expert, but I have been doing some research and APPARENTLY the LSD from the NA supra small diff will fit into the housing of mine for the LS400. And apparently that swaps into your diff too. I cant find the thread but I read a post of a guy doing the swap of the internals between the supra and the SC400.

So that means that our internals for the differ are probably closer, rather than further apart then one might think. As for the casing that's another story. The SC diff is a 4 bolt mount while the LS is just 3 bolts.
Again, remember I am a noob when It comes to Diffs, but from all the research I've done it looks like many of the internal parts are interchangeable.
stating that the 10 bolt supra Torsen LSD fits into the SC Diff. Being that the LS internals are also 10 bolt and apparently the same "A Series" type differential, the internals should swap nicely.
....But all of that is not my issue. I just need to know if my diff is okay! lol
