Ron are you talking about the 1 inch piece that come straight down off of the car where your side skirts are connected to?
If you are and ford wont fix it dont worry it is common for that piece to get bent if someone puts a floor jack on the wrong spot. Just use a hammer and maybe some pliers and get it as straight as you can then take some sand paper and clean the bare metal up and primer it then paint it. Since it is under the car where it cant be seen you dont have to have it perfect and with the right primer and paint rust will not be an issue.
