I am as confused as Keith S. ?
A bezel is usually considered to be a separate trim piece/part that surrounds something like a headlight bezel, a taillight bezel, an instrument panel bezel or a radio bezel.
I am not aware of a taillight bezel on the 2008 Sport Trac?? If you are talking about the chrome trim on the taillight assembly..I think it is an integrated part of the taillight assembly. If yours is damaged you will probably need to replace the whole taillight lens assembly.
