OK Serum i think i understand now, you say to make a special adapter to slip over the 8mm pinion diff, to use the stock revo slider?

I was thinking to just drill the stock revo center shaft yoke to 8mm and drill a hole in the 8mm diff pinion, like on the V1 modified pinion, and use the stock revo drive shaft pin to "lock" the stock yoke on the new diff pinion.
