SuperMaxx High Voltage Lightning

[CerberusVI]

Idk if this helps at all, but for one of my conversions I used a center diff out of a kyosho mp777 with a kyosho 52t lightened spur gear. Not sure if the diff would fit your mount, but its 34mm from bearing to bearing. The big spur allowed to me run better gearing around 43mph instead of 55+!
