Man, a ten or eleven year old car and you already can't get parts from ford for it, that's a bunch of sh!t.

It looks like a very make-able part, I'd think a good welding shop could fabricate one out of stanless steel pretty easily, but if you can't get the old one off that makes it very hard. I work for a large agricultural comapny and we have a local welding shop that makes stuff like that for us all the time, a few bends and a few welds and viola.
Look around for a good welding/fabricating shop I bet they can help, if you can give them the old one to pattern from that is.
