You are welcome Bob but, I wouldn't recommend doing this conversion unless you have the time and tools because an axial trans or an f-350 trans would be a lot easier.
It probably took me 6 or 7 hours to make this but, every time a drive it I will be rewarded that I made it myself. It should sound really cool when it is done because there 8 gears driving against each other from the motor shaft to the final output shaft and there are 2 sets of those gears in metal cases, the hpi GRU and the GRU I made.
No offense taken Steve!
