I'm not familiar with your exact installation but a hylock might work well?
I would use one if possible over a pin and cotter pin.

It's a hinge pin for crying out loud. Clevis pin, washer, and cotter pin would be excellent. Most people won't have the right length pin which is why I suggested a bushing made from 1/4 diameter tubing , retained with a screw and lock nut.
