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

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.

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 :)
