I wanted to move my windshield up from the middle set of holes to the top. Removed it, and immediately lost one of the rubber nut/grommets that it screws into. Purchased replacements, but can't figure out what I'm doing wrong. First, it's a major pain trying to fit them in the hole without falling through before I can get the bolt started. But I managed to get that done and the shield is not being held tightly. The rubber grommet slides in and out, so I ended up just taking it all off. I'm actually happy without the screen, if it didn't look so goofy wo I'd like to get it back on. Any tips? Did I lose some other part that I don't realize? Doesn't seem like it should be so hard to adjust the screen height. Thanks for any help!
