Historically we have machined new sideplates for the AM supershifter or Gen 1 although we have also added provisions for a third motor in some seasons. Per my understanding Andymark's fully covered gearboxes are more for legality and increased functionality in a greater number situations. (they can't get fingers sucked into them, they can be safely run on a table, and more easily interfaced to a great number of designs, etc.) Custom sideplates eliminate alot of functionality that while important for mass production/consumption may not be important in your design. This is traded off in favor of things like reduced weight, better packaging, more favorable gear ratios, etc which most teams find desirable.

In any case, we cover our otherwise open gearboxes with thin polycarb which seems to work well.
