Servo shifter for AndyMark transmissions

I have seen the AndyMark 2 speed transmissions adapted to use servos, however I couldn’t find any real details as to how this was done. I was wondering if anybody could point me in the direction of a whitepaper or something, or perhaps someone on a team who has done this could provide drawings or whatnot. Any help is appreciated.

For reference, here is a thread I located referring to such a mechanism. http://www.chiefdelphi.com/forums/showthread.php?t=37786

Thanks

Looks pretty straightforward to me. L bracket with some holes and a cutout for the servo. Fork shaped piece attached to the servo wheel probably. Bushing on the shifting rod. A couple nuts. And it’s done! Easy.

Or has anybody used a single pneumatic to shift two andymark duel speeders?

Team 45 themselves did exactly this in 2003. Plenty of other teams have also.
