I think that welding a solid 3/8 rod to the pedal and use a washer, hole and cotter pin to secure the clevis to the pin. That would be much better than using a bolt. Or like Dan suggested, get a longer bolt that has a smooth shank long enough to get past the clevis, and cut additional threads if needed so a nut can be run close to the side of the clevis. A prevailing torque nut and locktite would work, although I'd still use a washer between it and the clevis.

Looks like a good setup otherwise.
