OK I am really hoping on some help here. My son tried to be a help and began to change my headlights to brighter lights and when doing so, his ADHD self lost a screw. I have no idea what size screw to get to replace this but I can not put the rubber thing back on to keep out moister until I figure this out. Best I can describe it is ... There is a small metal bracket there after you remove the rubber piece and in google directions it says to try to avoid removing this metal bracket, but of course he didn't read that beforehand. It is a very tiny screw and the metal bracket actually rest upon that screw and then you put the rubber casing back on. Can anyone please tell me what size screw this might be???? I have Googled! You will save a child LOL
