I want to have a Stealth hitch put in so i can buy a bike rack to use. I noticed that my panel in the back facia of the vehicle does NOT have a cut out. The bike installers want to cut a hole in which to put the hitch but I'm concerned that when I'm not riding and want to remove the hitch receiver, there will be no cover to keep dirt, stones, sand, etc out of that area. Has anyone else found themselves in this predicament? Does anyone know if Tesla sells a replacement plastic panel WITH a cut out that i can buy?
