Like I mentioned somewhere else on here, I have my CB mounted overhead, with my wiring running down the A-pillar, so I decided I would hide it all with the plastic piece I assume the fancier trucks had, so I go to both of my local junkyards and look at probably around 15 trucks, of all varieties, C10's to K30's, Suburbans and Blazers, all varying from custom deluxes to Silverado/Sierra's, the oldest being a 74 C20, and the newest being a 91 K5, None of them had the plastic pieces, am I just going on a wild goose chase looking for pieces that don't exist? LMC says they do, but that's the only place I've ever seen them.
