Tri Fold Bed/Tonneau Cover Part

Hi guys -
I am new here and just bought my fist 2017 Tacoma Sport last week!

There is a plastic part missing on the passenger side of the tri fold bed cover and was hoping someone might recognize what it is and be able to give me a part number.

I have Googled a bunch, but I can't find this exact part. I even saw a few exploded diagrams of the cover, but I don't recognize what this piece would be called. It is a plastic cover that fits on the outside edge where it folds (nearest the cab). I put a red circle around the piece in the attached picture (from the driver side).

Thanks in advance!

 

I no sooner posted this topic and then found this part (but it says driver's side). Does anyone know if it could be the same part that fits the passenger side?

The fact that the ebay item shows an OEM part number tells me it is sold separately and if it is different, the dealer should be able to provide you with the part number for the passenger side.

 

Here is the part number for anyone else who may ever need it: 64915-04010
