Review on Cabin Air Filter Cover - Compatible with Cadillac, Chevrolet, GMC Models - Part Number: 22759208 by Jerry Anderson

Removed the floor panel on the right side of the cab. I then used a dremel with a cutting wheel to cut a rectangular piece along the visible lines to make a hole for the filter. It didn't look perfect like I was working at my workbench. I then used a sanding tip to smooth the edges. The filter included in the kit fitted perfectly, as did the new plug to fill in the cutout. The camera already has a hole for the supplied screw. One end of the skid plate hooks into the back of the plenum and attaches to the front where it screws into place. I know it works because I no longer get stuck in the rain with small debris when I turn on the fan.
