I have a piece of 1/2in PVC pipe running thru my bumper with one end having the cap permanently attached to it. On the other end the cap slides over the PVC and a clevis pin holds it on. Been doing this for years and have never lost a cap since. It`s easy and cheap and you don`t have to drill thru anything but one end of the PVC pipe.
