I just called the dealer's Parts Dept. They said the Ford Performance sill plate is part of that entire trim piece and costs $191.00 EACH and has to be ordered (4-5 days).
They said if I want it installed through the dealer's Body Shop I'd have to stop by and they would write me an estimate.
Now I haven't looked at it yet, but I'm guessing it's something I could do myself. Going outside to check now, will get back to you ...
UPDATE: That piece of trim is 2 1/2 feet long and extends forward past (and behind) the hood release, and back towards the area of the middle of the front seat. That's why they're $191 each, so with tax it'll cost over $400 for the pair. I don't see any visible screws, so I'm guessing it just pops out?
