The total width of the vex slot is 0.821 inches. AndyMark uses 0.48", which in my opinion is reasonable. We've used 0.275" in the past. Vex's ball shifter requires perfect cylinder alignment, but it works because they have a nifty coupling, the same that's used here.
The three CIM DS gearbox confuses me. There is 1.316" between the plate and the gear closest to the plate, and there is nothing in this space. I understand why this room is useful if you're looking to add a PTO with a pulley, but I don't see why that extra space is there in the normal model. The could probably sell spacers that are 1.25" shorter, and have shorter shafts.
