Lexus diff codes

Does anyone have information about all the differential codes on the diff? I am not talking about the door codes. Like my diff has 381 sticker on the diff but some diesel models also have 32H. I would like to know what is the difference between these. Like what does those codes mean?

Like on is300 there are:
M96, M98, M85

I think all of the ISC get the same wide flanged case as the 350 and LS460, F's but retain the 4.08 ratio.... That leaves the 250 stuff and BRZ/86.... I haven’t done much looking but there is this from the ISF forum. Give a thanks to @Hoonee46 for that.

just completed the swap. Sport mode, nannies on: i punched it from a stop, turning right, and the tail kicked out right away, no one tire fire and no sudden jerks from elsd, then car started beeping at me and smoothly straightened out. I'm in love all over again!

So conclusively these will all fit the ISF:
IS-F open diff: 48J...
IS-F LSD: 58J...
LS460 open diff: 32J...
LS460 FSPT LSD: 36J...
- The actual part# for the LS460 LSD is 41110-53292 same as 12+ISF
