Need help

Does anyone know what and where I can get this black piece? I'm missing the passenger side. It's behind the cab. People said it's a vent cab but no where online has that piece. They just have the vent only. Here is driver side picture

No problem, does this look like it is it?

I have used GM Parts Direct to help me find parts and part numbers in the past and it seems like they don't have that black cover piece.

Does that cover piece have a part number stamped into it?

2016 doesn’t even have the cap. I ran my cb antenna wire thru that cab vent.

 

Hit up a pick and pull junkyard for the part.

That's odd that they don't sell that cap over the vent. I have it and my brothers 07 Silverado 3500 HD also has it. Do you think it's a 3500 series that only uses it? Also further inspection, I notice gm uses some glue to hold it together, no no bolts or clips.

I wouldn't think that it would be only for a 3500 series but it is always possible, my grandfather has a 03 Silverado 2500-HD, When I see him this next week, I'll take a look and see if he has one.
