Can anyone confirm if the cush drive from the XO-1 will fit in a Stampede 4x4?

I imagine the bigger spurs are totally out but maybe the 46 tooth will fit?

Also the gearing might be right out? Might need smaller than a 9t pinion or something?

I'm just asking as I've got a heap of Mod1 pinions and it would be a strong part in the Stampede.
