Gearbox
I need approximately a 7:1 reduction. I first planned to put the motor on top of a mini gearbox and connect them with a belt, but I got nervous about the strength and lifetime of the belt. I've now got an old stock reconditioned Mitsubishi Mirage gearbox from the early 80's. It's got 4 gears plus overdrive and input shaft doesn't need to be supported by the motor. The box & motor just fit with no modifications to the subframe. The input shaft is diameter is big enough that it can be cut down to fit the motor.

Reconditioners neglect preload!

Needs to be On-Off-On type. This looks good -- locking lever.
