I'm missing a trim piece in the tail gate area. Below are pictures of the driver side which is missing the piece and the passenger side which has the piece. I've looked through the parts diagram but can't find this trim piece. Anyone have any ideas on the part number?

 

That trim piece is for the OEM rear cargo cover that pops in those slots. You can either get the rear cover or replacement piece for the other side. I really like the cargo cover to hide stuff for shopping and traveling.

Thank you very much. I never would have found that. Shipping costs more than part.
