I really like the idea of the rear door sills w/ the Prod. # on them.
Here is a pic of the front Focus SVT sills installed to give you an idea.
Some one mentioned earlier about a blank to put in the oval. I had some free time a while ago so I figured I'd try experimenting and made this. I had this grill and rear insert in prior to painting my extra grill and installing Stazi mesh all around. They are dirty and dusty from being stored for over a year but you get the idea.
