Recheck the blind nut and repeat the above steps if necessary. Note that overtightening the nut can damage the threads, rendering it unusable. After installation, remove the blind nut installation tools.

Using the same tools, pass the existing bolt through the smaller mounting plate. The ball head bracket should be at the bottom, as shown in the picture. Install the tailgate safety tether and tighten it completely.
We provide polyester film to prevent parts from sliding on the truck bed and tailgate. Apply the polyester film to the truck bed and tailgate, especially where the tailgate auxiliary components will be close during opening/closing. The arrows in the diagram indicate the installation location for the polyester film. The vehicle shown in the diagram is only an example of polyester film installation. Your vehicle may differ from the one shown in the diagram.
