You do not need a template.Here is the easy way to do it with normal tools.
Deep well socket, 3/8" or 1/2" drive and a transfer punch 3/8" or 1/2" Dia. depending on what drive socket you use.
Take a deep well socket set and find one that fits the scoop holes in the under side of the hood. All 70 and 71 Dart hoods have these holes. 72 hoods have both sets twin and snorkel scoops.
Find a transfer punch or make your own to fit the square hole in the socket. usually 3/8" or 1/2" . Put the socket in the four holes per side upside down and transfer punch a dimple from the bottom up. These four holes are important to be centered for access to nuts .
After you have these done drill them with a 1/4" drill bit. Then turn the hood over or close it and set the scoop in place. You now can locate the other four holes with slight pressure on the scoop putting marks in hood. Drill all holes to 3/8" using a step drill and you are done. This is the best method to use and how I have done it for years. lining the holes up to the inner holes is important and you cannot screw up this way. I also use this method to install factory hood pin sets.
All hoods that were available with factory scoops or pins have the inner holes in place. It is better to locate the holes using your inner holes than to use a template.
Remember to use the proper bell nuts or the scoop will not pull down on the hood.
When doing the scoops on a duster hood they didn't have scoops in 69 or 70 so they do not have the inner holes . To place a snorkel on a hood that does not have the holes on a duster or dart the center hole in the rear is 4" from the rear edge. I just did a Duster yesterday. It is a little tricky for the side inner holes they are on the angled part of the inner. 4" from the rear puts the center nut in the front behind the V on the inner.
Why pay for a template that may screw you up in the end use the holes that are there.
This post may be taken down again as it was before? but I have it copied for the future.
I found this for the 4" hole can be used with a bolt.
