Marked the cutoff lines on the right skirt. I marked a ¼” line on the bottom of the skirt, but used a ½” line for the upper and back of the skirt. Used the dremel with a cutoff wheel and removed the excess. Then I sanded the edges—discovered that fiberglass is every bit as sharp as cut aluminum. Figured out how to judge the angle to drill the lower tube of the rails—just slide the skirt to the rear a few inches and it’s easy to see the angle needed so that the skirt properly contacts the tube—duh.
