73 Duster scoop

I dont have a pic of the underside of the hood to show you but there should be two round holes towards the back and they are about 2 1/2 to 3 inches apart and they are 4 inches round with a foam type ring around each hole. The holes sit side by side a few inches forward of the back mounting screw holes. You are in the right place. Before the nights end someone is gonna post a pic and I am sure someone has a diagram of the exact location/size for the holes. Good Luck!!
