Just look under the hood in the area were the emblem would be. There will b 3 circles about 3/4 in diameter in the under bracing. the emblem gets placed thru the hood. A sheet metal nut would be up against the hood skin in that area ,not thru both layers. if your hood was not drilled & you have the reliefs in the underbracing , then you had no emblem.( wich is very odd & rare) 71 emblems have pins that go thru the hood.

As a side note ,AMD forgot to put those relief holes in the under brace on their Cuda shaker hoods. Another problem with repro stuff-its never exact!
