Don't forget if you bolt the flywheel on, you'll be adding a thrust load to the motor shaft with the clutch engaged. It may not be designed for that (you might have to design in some bearings to deal with it).

You could also probably pretty easily machine the splines off and then use a regular taperlock style hub/coupler.

And you know... if you could engineer some way to use that lame "slot" style pump shaft (some kind of stub shaft held in place with a support bearing?), you'd be even more famouser than you are now. Everybody else doing a budget conversion who ends up with one of those motors would be in your debt.

Have you asked Guru Husted for his advice yet? I haven't checked DIYelectriccar.com for a while.
