I added the rear vault and sill plates on my 4dr OBX. Both were very easy and quick to install. High quality materials.
The sill plates are expensive for what they are. I would have liked to see them bigger with greater coverage (as compared to my F250). They are defiantly shinny!
The vault was very easy and quick to install. If I had to complain about anything it would be that the Ford Oval is upside down once it is installed.
I also added the rear cargo area mat. it is a perfect fit and looks great
