I'm thinking you will have to relocate the radiator and install an electric fan for it and you have to have a custom adaptor made to mount the clutch you could use which ever end of the motor makes it fits best and save on buying the gears.
I like this build, to bad you're not doing the whole job.
(I'm betting you might end up with it before it's over with!)
Edit: That is the control bax for the Club car, throttle lever, micros, soleniod, voltage regulator, fuse
