diff application question
 

im currently looking at picking up a tomei trax 2 way differential for my drift car im building and im a little confused looking at their application chart. i have a t2 rear end from an s4 that came with the factory clutch type lsd. tomei only lists diffs for turbo open rear and viscous.....no clutch type

Attachment 659621

they have the same product number for FC open diff, FD and RX8 and i know fd diffs fit in t2 housing without having to swap stub shafts (since i already have s4) so im thinking the one listed "open" would fit? i just wanna confirm this before i spend a small fortune. thanks

in Japan the limited slip diff was optional

Does anyone know if the open would be the right one to use
