Shown are the components that come with the deflector.
I went to the local hardware store and picked up the fasteners noted on the bottom.
The supplied plastic ones did NOT hold well enough in my opinion.
The clear bump-stops were installed after making a run on the freeway, and noting where and if the deflector could contact the hood.
It does bend down a little at speeds over 75mph, but nowhere near enough to touch the hood.
I'll update with a pic to show the installed locations of the bump-stops.
