Looking at the pic of the different parts of the Hybrid Diffs, it really looks like the input shaft is 8 mm with the tip machined to accept the Revo shaft. I'm sorry I can't be 100% sure but it really looks like you need a 12X8 bearing like magman said.
Mhh but what change on V2 and V3? I wrote mike a mail, but no answer.
Titan :/
The v2 uses different size diffs...HB Koysho, etc and hence different size bearings. The v3 uses Mugen diffs
