Where can I get a sticker for the rim of a 2007 Mustang GT?

My dad has a 2007 Mustang that he's in love with. If you know what they have for the original rims, you'll know there's an oval sticker in the center that says "Ford" on it. It came off of one of his rims. I was wondering if anyone knew a website or anywhere in general to find a sticker for the rim.

I don't know if they are stickers. They may be caps. Check out this link to see if this is what you are referring to:
