If you can fine another gear just like it, you can simply integrate it into your gearbox by making the correct shaft for it.
Most years there is no need for the throttle motors, as many mechanisms can simply be powered with pneumatics (6 cims, 4 minicims/bags, 4 Banebots motors, plus some others is a lot of motors) . As a project all on its own, making a gearbox for it would be interesting. I believe there was a similar attempt to use it on here recently.
