I would like to replace the OEM matte black with the OEM gloss black. Which models did the gloss black come on? Would anyone know the part #s? Thanks

 

I tried to do the same thing, found out just getting a pillar cover on ebay was way easier, cheaper, and looks great. Take your time putting them on, and they look completely stock. just ebay search "pillar covers" and find your exact model. Cheers!

 

I got mine on ebay. Install was easy and they look great on a black truck with tinted windows.
