Hidden deep in the trunk of the fastback, this part was found. I have no idea what it is, other that some sort of bracket. It has a ford part number stamped into it and it is: C5AA-2888-D. And here's a couple of pics, they're not too good but you can get an idea of what it looks like:

There was also another part that was laying in the trunk when I bought it, but for the life of me I can't remember where I put it....
