FC Turbo II R&P vs. FD R&P

[Whizbang]

I know the Torsen from an FD fits into the Turbo II but what about the ring and pinion? I am in a quest for a ring and pinion option for my turbo II rear end but nothing has come my way. I know Knight sports make a 4.77 for the FD so i am hoping there is some cross compatibility.

okay so these seem to NOT be interchangeable....i wonder about the front carrier...

Rings are the same.
Pinions are different.

Both 8" right?
And RX-8 is 7" right?

I will try to adapt some Toyota 8" Ring&Pininon into our TII diffs, probably 4.88 ratio :)

RX-8 is 8" AFAIK.
