Dual Hood Scoops Functional
What are you putting the scoops on - what hood?
The 1970 340 Darts all had scoops with holes in the hood. I don't think any of the Dusters that used these scoops came with holes from the factory. Installing the scoops and cutting the holes is a piece of cake on 70-72 Dart hoods because of the factory holes for the studs in the hood frame on all the stock hoods, and the crescent cut for the edge of the big hole in the frame. getting the hole the right size is critical because there in a gasket that goes in each hole to keep rain from running up the hood and into the holes and onto your engine. Gaskets available from DMT and other sources.
I have a commercially produced template for installing those scoops on a Duster hood if you want to borrow it for the cost of shipping both ways. PM me if interested.
