I bought an '04 2500HD that didn't have the tow hooks or the front valance that will accept them. My valance had no openings and was in great shape. Rather than spend the $$$ on a new one with hook openings or a used one with problems, I decided to convert what I had. It's pretty simple. First remove the lower valance. Note: All of the work is done on the back side of the valance. From the back side, sand down the innermost coves on the edges. Use a small handsander with large grit. It takes some time to get to the point where you can see where it wants to release. This plastic is TOUGH! It took me about 20 solid minutes on each opening. Remember, you only need to be concerned with sanding the point where the plastic connects on the fold - you don't need to sand the entire opening. Once you get close, get aggressive and work the areas that need help. Get it to release on its own if possible so it looks factory smooth. One side of mine released easier than the other. At a point you can just pop it out. Don't do it too soon - the plastic gets pliable since it's warm and will tear into good plastic if you haven't removed enough for a clean release. Use the edge of a blade and drag (not cut!) it around the edge of the cutout to remove any hairs. You can also use some finer grade sandpaper to hit the edges. Remember, when you do any cutting or sanding stay on the area that was removed - any cutting into new plastic, well, looks like you just cut into new plastic. This is what we're trying to avoid. Mounted the valance back up and I was very pleased with the results. Looks factory, saved me some $$ and I don't have an extra valance to add to my spare parts pile. Now I just need to install my ordered hooks.
