Idunno. Look at the end in the passenger side pic. Looks like pretty deep flat sided channel rather than the formed original. Also, the fact that it's held on with foam tape seems to indicate that it doesn't have the curved edges of the original. Seems like it'll collect a lot of dirt.
I guess it's ok as long as the buyer understands what he's getting.
