Great look'in truck. You did good on that one for $250. As mentioned the Grille Guard on your truck was indeed an Accessoery Guard from G.M. They were manufactured for G.M. by, Cello Products Co.(A Division of A.S. Campbell Co.) of East Boston, Ma. They usually sell on ebay, in good condition from $150- $350. I've owned several, & still have a couple of NOS Guards like this, in my Shop. See one of mine here,
