Hit up your Ford dealer again and get a part number for it, see if they have it but check eBay and surrounding dealers in your area.
I have had to do that for a few specialty parts, sometimes my local place has them cheap and sometimes they are a complete rip off. One time I needed copper washers for brake lines and they were $8 each and they wanted me to buy a minimum one package of 10... fawk off. But they have been really good about other things. It's very hit & miss. A part number will get you started.
