For some reason GMC's get the bum end of the Aftermarket attention... Really even with the upsurgance of Advance Design pickups(late 40's to Early '55),later '55-59,'60-'66,and '67-'72 trucks, GMC only gets a Fraction of the specific replacement parts....
I have a '77 GMC which was the first year for the '77-80 Grille insert design, and I am pretty much stuck repairing mine, or doing a Salvage Yard crawl for one(Extremely Rare to find one around me, as they have usually been already nabbed for Flea-Bey, or it was trashed while some idiot was in a hurry to get the Engine out)
