Looks like they are called eyebrows...available on ebay

 

Thanks but those are the ones I already bought from ebay before and they were flimsy to start with and warped in no time, Need some real hard sturdy plastic ones, cant seem to find the good ones

 

eh, i tried looking for ya. no luck on "solid" plastic. i'd just find some plastic sheets and cut my own. If you need some bend in it, take a little heat gun to it.

 

Thanks that is my last resort, was hoping not to have another DIY project but at least this will be a really simple one

 

i bet these were solid. seems they don't make them anymore

Yes in one of the pictures it looks like they have dual ribbing on top for support,

If I have to make my own, I may even try putting in one of those heated mirror kits instead as this is really to keep the mirrors clear of snow and ice in the winter

 

My ebay ones are looking very sad, and this was six months to the day after installing them, and it didnt take that long for them to look this bad. They look even worse now after over one year on the car
