My 1970 340 Dart has it's original dual scoop hood on it. I have another hood from another 70 Dart I used to own that I want to put a dual snorkel scoop on to put on the car in place of the dual scoop hood. I was looking at the hood that I want to mount the snorkel scoop on to locate the scoop stud positions per a photo I found on here from another thread on the subject. It turns out that the hood doesn't have any of the factory stamped holes in the sub-structure on the underside that are shown in the photo, So I looked at my dual scoop hood that is on the car and it has the factory stamped holes as per the photo even though they aren't used for the dual scoops. Were there two different hoods (beside the scoops being added) that they used on 70 Darts? Also, is there such a thing as a template available for locating the stud holes from the top side of the hood?
