I was unaware when I ordered it that it did not have the mounting tabs of the OEM covers. Instead it has a flat, oversized blank surface that the buyer has to drill holes through, after first locating where the spot to drill the cover corresponds to the grommets in the frame. Then, if the holes you drill line up right you would put a screw through the cover and grommet and then place a nut on it. Then you must make sure you tighten the screw the right amount. Too loose or too tight, both are bad. Finally, once finished mounting it, you're left with three visible screw heads. Lastly, there are other sources of replacement covers that are exact copies of the OEM and use the same mounting tabs.
