Takedown's E-Warhead Build

[Takedown]

My motor has an 8mm shaft on one side of the motor and a 10mm shaft on the threaded side. I want to shave down the 10mm shafts into a 8mm shaft to match. Heres my motor- http://www.hobbycity.com/hobbycity/s...idProduct=4907
My drivetrain is very tough. I havent heard of anyone ever having issues with with their warhead diffs/bevels. I should be fine. I am going to replace the cvd pins in the arm cvd's because their very worn and Im afraid they'll snap like a twig under the huge stress they're about to under go.

BTW: Ill look into that 8mm metal revo yoke. Kinda pricey for just one yoke but I guess it'll do.
