HELP!! dual factory scoops on a plain 1970 Duster hood

So we are getting ready to take a nonscoop Duster hood and put factory (1970 Dart, 69 Superbee) scoops on it (and yes we'll cut in the air holes). I've done this a few times on 70-71 Dart/Demon hoods, but we flipped the Duster hood and there are NO CUES like holes in the underhood frame of a Dart hood that make that so easy. Can some of you guys/gals help us out by posting some pictures of original Duster hoods with those scoops installed? We are looking for shots of the underside of the hood so we can see where the holes are in relation to the hood frame. We could also use some basic measurements like the distance from the middle of the back scoop edge to the back edge of the hood and the distance from the front outside corner of the scoop to the side edge of the hood. Of course if somebody is making a template we'd be glad to buy one!
