The panel is made of plastic and is damaged and is unuseable as is. In fact, the panel is scrap. There are 10 holes in the panel for mounting to the car. 3 clips were attached to the panes and the 4th clip was loose in the box. I tried the 4 clip in the remaining 7 holes and it would fall out. That is because the holes were all chipped/cracked and/or damaged to the point the clip would not hold.
