This is a complete bolt on FRP headlight cover. It is designed to “peal” off the correct amount of fresh air delivering it to the engine compartment without disrupting the flow of air over the car. Mounting tabs/ brackets are part of the cover, not something that needs to added. To install you simply unbolt your factory headlight cover and bolt on your new cover.
The final sanding and prep for paint should be done before installation. Slight trimming or adjusting of the bolt holes and mounting tabs may need to be done for proper adjustment when installing
