This is a gross overstatement, when talking about transmissions and LSD's.
While most of it is true, the differentials are different from say gsr to b16 and ls and their final drives.

However, for the initial question:

The ring gears on the Type R and GSR are different from the LS/B16 differentials as the bolt pattern is spread out. I believe that the Civic Type R was the only transmission to receive the crappy roller bearings, make sure you shim it right or else your in for quite a suprise....

You will need a 4.4 ring gear from a Type R or GSR transmission.
