Parts and Tools Needed:

• Tape Measure
• Marker
• Drill
• ⅛" Drill Bit
• ¼" Drill Bit
• Rivet Gun
• ¼" Ratchet
• 9 mm Deep Socket
• Safety Glasses

Step 1: Remove Rocker Panel Molding

Use your hands to pull on the rocker panel from the top down. You may need a plastic pry bar to remove it, but just your hands should do the trick.

Step 2: Remove Original Clips

Drill out the rivets holding the plastic clips in place. There are six clips in total

Pro Tip: Once the panel and clips are removed, it's a good idea to clean the body of your Mustang to remove residue that may have built up under the panel.

Step 3: Line Up Rivet Holes

The rivet holes from your original rocker panels will most likely be pre-drilled and in the correct location. However, if any part of your Mustang's side molding has been replaced, you may need to drill new holes.

The top hole needs to be ⅞ of an inch from the top of the rocker. You can measure the distance to the bottom hole by lining up the original clip with the top hole.

Once the clips are lined up properly with the panel, make sure they're in line with the other clips as well, then drill the holes.

Step 4: Attach New Clips

Use a rivet gun to insert the rivets provided with your rocker through the new clips and into the pre-drilled holes. Repeat this process for all clips.

Step 5: Drill Stud Hole

To attach the new rocker panel, there's a stud that will need to go through the side molding.

Line up the panel with the clips and drill a hole for the stud where it lines up with the corresponding hole on the panel. Insert the stud and place a nut on the other side.

Step 6: Install New Rocker Panel

To install the panel, start by attaching the bottom clips. Because of the length, it's probably a good idea to get someone to help line it up.

Next, slide the rocker panel into position, attaching it to the top clips.

Congratulations, you're all done!
