I just had the dealer put mine on a couple days ago. I have an invoice with a part number if anyone wants to know it. They used self tapping screws.
The bracket is formed to fit perfect over the center line of the bumper and is also formed on the sides to fit the bevel profile on the bumpers. It does not look that bad...I will post pics this weekend.
In Minnesota you can and will get pulled over for a ticket, it happened to me and the officer wasn't going to listen to any 'excuses'. Says he heard them all before.
