FYI What you refer to as rock guards are properly called segment protectors. Lots of people confuse the two. Rock guards protect the windows. I would be interested in buying them all but probably there is no easy way to get them to NM. You can easily drill out the rivets with a 1/8" drill. But then you have a hole. The best way to fill the hole is with Olympic rivets which are blind rivets you can install with a rivet tool,
