YOu can use the gearbox, but you have to take the motor part off of it, and replace it with a kit motor. You should buy some extra pinion gears so you can just put a new pinion gear on the kit motor, instead of having to try to remove the gear from the motor that you can't use.

We used that gearbox on this years robot by changing to a kit motor, it works fine for turning our turret. We have a V belt drive, so it can slip, which is an important safety feature to keep from burning up the motor, since our programmers have been very challenged trying to get the limit switches working.
