When I ordered the new shield, my dealer was also kind enough to soak me for $2.37 each for new plastic inserts, mine were loose also from years of removal/re-installation. They were listed as a nut, part #30683256. FYI, on the parts computer screen the screws and plastic inserts are shown as bolts with washers and metal nuts, but when he pulled the parts with the same part numbers they were actually the correct inserts. Screws are a coarse thread T30 screw.
