Help needed on duster 340 hood scoops

I was wondering if someone has measurements or a pattern for the holes in the underhood bracing to access the dual 340 scoop mounting studs.My 71 duster came with a stock hood and has no holes underneath for the dual 340 scoops-the few Ive seen in person have holes in the structural bracing itself for access to certain studs-hope this makes sense.Any and all help is greatly appreciated-I dont have easy access to an original 340 duster hood even though my car was an orignal 340 car lol-but it will be returned to its former glory!.
