Folks, somewhere on my basement floor is one chainring bolt for a TA 3-pin (pro 3 attaches) crankarm. The diameter of this bolt is narrower than standard coupling bolts, so I can't swap in just anything, and the black hole that is my basement floor seems to be defeating me. So, if anyone has such a bit that they'd be willing to sell me, I'd appreciate it.
