Jeff,
One of my friends has a 70 Mach 1 with the non functional scoop. It's just a standard hood with the scoop bolted on, and looks just like your old car's hood underneath. Shaker hoods are the same stampings, with the hole cut out (as well as the twist lock holes) and a trim piece added to cover the edges of the cut. His car is a late 1969 build date as well. Your build is looking great, especially opening everything up!
