It's suppose to be a slight alignment helper, and works as a "retainer" when you actually unscrew the bolts so it doesn't fall off and wreck the paint. I myself just got an OEM wing for my Hatch, and now I have to figure out what to do, and if I can get that little orange clip or not.....Does anyone know what the orange thing (2nd image) is for the middle screw (1st image)?
