larger inner diameter is 66 and belongs to a GSR/Type-R 4.40final drive.
so....the smaller one you have is a B16, and the larger is your GSR/Type-R
Thanks for the input. So, there are only two 4.40 rings gears then? The case said J1 , but anything could have been in there. I have a aftermarket clutch type lsd hooked to the ring gear and am unsure what else the lsd could be used with.
So the answer is .......... its a gsr/itr compatable LSD. Jackpot !
