reproduction trunk wheel house seam cover for the Ford Mustang. I have actually never seen an original pair of these on a car, but they do serve a purpose if you are in the habit of cramming your trunk full of items you do not want scratched. These attach to the protruding seam where the inner and outer wheelhouse bond together and measur about 14" in length. You will have to modify these to fit your Cougar.
Replaces Ford part # C5ZZ-6531466-A.
