Hi Guys, my uncle is putting a Demon dual snorkle fiberglass hood scoop on his 73 Duster. He was told the holes under the scoop are supposed to be 4 in diameter. He has purchased two gaskets for them. He wants to make sure this is correct. Does anyone know the size and position of the two holes under the hood scoop. He wants it to look like it was a factory option for the 73 Duster.

Thanks Scott!
