Just spreading the word as I just found out about these. HELP (motormite, Dorman) makes a replacement plastic headlight gear for about 15 bucks. Autozone can order them, but it may take a few days to get them in. Part # 42400.

There is also a metal arm that helps hold the cover in place being sold by someone. I'd have to look it up.
