Dart/Demon twin scoop locations

how did you locate the spots for the #1 holes.

the big holes in the hood frame (underside) are already there in 1970 and 71 hoods whether they came with scoops or not (see picture)

they are also there in 72 hoods, along with holes for the big dual snorkle scoop, but you have to be careful to use the right holes!!!
