It looks like the motor face and diameter are about normal for a Citicar, and since it has a female spline an adapter (like used on D&D motors) might work. All speculation at this point as I haven't called them.
I don't like the Citicar rear axle/differential I have as it makes a lit of gear noise. If I do an AC upgrade, I'll probably get a golf cart diff at the same time. Then there is the problem of the speedometer/odometer...
