A roll pin connects the triangular central piece of the shifting mechanism to the shift shaft (that tiny one you can see in the photo). It went through the output hex shaft through a clearance slot, which isn't shown in the photo. (EDIT: I've been told that it was a dowel pin, rather than a roll pin, which is stronger.)

I hope that this doesn't get lost in the game hint chatter. This really is a huge technological leap, and a great experiment, similar to how a ball shifter was a few years ago. It's just a pity it took 3 weeks to machine. If it didn't, I'm sure 971 would be rocking it next year. I have to hand it to Travis, Austin, Brian, and co for pulling off such a innovative, different and cool idea.
