Oh - but I do like the idea of having one double-ended piston drive both shifters. Since the high gears must be on the motor side of one gearbox and the wheel side of the other, this is probably not a COTS gearbox, or at least a reconfigured one.

I thought for a while that these might be AM Super Shifters with the spacers instead of the extrusion, with the one on the left in the picture built with a lot of pieces backwards (both plates, and the plates on the left gearbox in the picture flipped so the shafts line up, as well as the high/low swapped on the dog and drive axles). Even with all that, the location of the gears on the shifter shaft don't quite work out; one side would be in low gear while the other was in high - am I missing something?

Here is a picture of the mounting plate for the super shifters. We used the same drive layout last year and had no problems. We added the additional wheels in the center for more traction. How strong the frame will be we will find out if this years game allows.
