Thanks for the help guys. I had no luck searching on the Tinnerman website while I was at work today. Seems they make every kind of trim clip except that one. So, I decided to take the dreaded drive to the dealership after work and see what they could come up with. The guy behind the counter seemed like he had never seen anything like it before, but he did pull up a part number and a price. W713508-S424 for $20/ea.
I came home and googled it and found it at Tasca for a little over $12 + shipping (LINK). It's listed as a part for a Taurus but looks exactly like what I have. I'm not sure why a little piece of bent metal costs so damn much though. Ford is really screwing us on that one.

 

Same issue as you I believe. I have an 09. Did that clip you bought from Tasca work for you? Here are some pics of the clip I have (well the broken clip anyway. The two separate pieces I have no idea how they go back on) Thanks for any help!
