1. With the help of my friend Jim, I removed the skirt, taped the aft part of the canopy with blue painters tape, and drew some lines on the tape denoting the location of the frame holes.
2. I cut several rubber grommets and inserted them into a few canopy holes as guides, then we put the skirt back on.
3. We adjusted and re-clecoed the skirt a bit to get a good fit. I extended the tape lines down onto the skirt, and marked where the lines crossed to determine the location of the six new holes that will be drilled at the back of the skirt.
4. Along the way I determined that there were about eight holes in the skirt that could use a bit more shimming, so I marked them, then removed the skirt.
5. Ground off the truck bed liner from the marked holes, then applied more carbon fiber shim layups to these locations.
