Billet grilles

I am trying to find a billet grille that is at least 36 inches long by at least 10 inches tall. I've been told to try an f350 or excursion grille. All of the places that I have called about this tell me that they don't have the measurements and can't help me.

I'd rather not go to a dealership and start measuring on their trucks just cause I don't want to be harassed by salespeople so if anybody has one (or something else of that size) that can measure their grille for me it would be GREATLY appreciated!! Thanks
