Started off by first test fitting the aluminum pieces and marking them with a permanent marker. I took the aluminum panels off and marked the holes. I then drilled the holes into the aluminum and placed the panels back on the frame. I then drilled through the holes into the frame. I removed the aluminum again (and cleaned off the debris) so I could lay down the silicone. After placing the aluminum back on the frame I then used my trusty air rivetoer to rivet the aluminum.
