Kraig -
Got a picture of the strap/pin that was used with the truss-head screw so ya didn't have to use a nut/bolt on the front holes? Thus preserving a "smooth look"...
And again, removal of these truss-head screws (along with the slotted style on footrests) requires use of a drag link socket.
Also, it has been determined here in the past that if you used a standard hex-head capscrew in the rear hole on the left side, you'd be in a whole lot of hurt under certain extreme turn/axle pivot conditions.
