CHMSL part number needed

need the part number for the CHMSL(with cargo lamps) and gasket for a 96 K1500 pickup 2 door. Been looking around online and have found a CHMSL but the place don't have the gaskets(unless it comes with). The copper strips have pretty much corroded out on mine, I think 1 brake light bulb works and have no cargo lamps, but have power at connecotr

Gasket is a delaler item. I went to a bone yard and got a good used assembly for less than 1/2 of new.

ordered from partsdirect. The gasket is included in the bulbholder assembly. part number 16522433
