Hint #1: Look carefully at the front of the Bosch motor, then examine the plastic motor retainer on the back of the stock Bosch gearbox. Notice the two round holes in the motor that fit over the two round pins on the gearbox, which prevent the motor from rotating when it is applying torque.
Hint #2: One the front and back of the Bosch motor, there are two ~1/4" square indentations, spaced 180 degrees apart. Seems like they are perfectly located for alignment/retention locks, doesn't it?
Hint #3: Take a look at how the hold-down strap for your car battery works.
We are also going for the dual-motor, dual-speed transmission, updating our design from last year. Throwing away the Bosch gearbox, and just using the motor directly into the transmission saves about 2 pounds per side of the robot.
