I took the rear wheel off for the first time a month or so ago to have a new tire mounted. When I went to reinstall several weeks after taking it apart, I cannot find the part that I think is called "rear brake panel stopper bolt" -- at least thats what the downloadable Honda Service manual calls it. That manual is the only place I have seen a decent picture and description of whats going on there. I've tried looking for the parts on the different parts fiche sites I've found links to so I can purchase replacements, but can't find them listed. It looks like its an 8mm screw (or maybe shoulder screw) with spring washer, flat washer, nut, and lock pin. If I can find a screw, washers, etc that fit (say at an industrial fasteners store locally) can I safely substitute them?
