Looks like the basic idea is here. I need to mock up a new emaxx tranny with the 1/8 diff on top of one of the 2 speed output gears. The diff output shafts can be made out of a modded revo output shaft. Does not look too difficult to do. I will have a machined part made to attach the gear to the diff. No other way to do it, unless I can drill and tap a spur or diff gear.

So my next question is: Is there a metal spur gear, or diff gear that is not hardened and will fit a hpi/ofna diff cup? Maybe a cheaper rtr gear or something off a low level vehicle that will fit? I just know from experience that hardened steel will not be easy to drill, and most likely be impossible to tap...
