Went to install a shorty axle today...just to realize it is a 50cc one.
It is made differently but I still made it work for now. I had to modify one of the gears for everything to fit right and turn without any binding. I still need a stator so I have not been able to take it up the road to test but it does spin freely and quietly.

This is what the inside looked like when I first pulled the cover off
