Is there a replacement part for this? Or does the little rivetted in holder just drill out and you replace the nut? None of the parts diagrams actually give a part number for it, but 2011 shows it as a separate part...
2011 has a black plastic washer under the seat pan that is a tight fit on the screw. It acts as a screw retainer. Unless I'm mistaken there is no nylock on the riveted nut assembly.
