I bought a NOS grill insert of of Ebay , it was in a GM box dated 3/99 but i can't find any part number on the part also the rectangler openings are all silver but the original insert in my 70 c/30 is only painted silver on the edges and it has 1 inch black edges every 7 inches . So what do you guys think is NOS and GM just got sloppy or did i get screwed
