Don't know if this will help you or not. 10 years ago at an MCA Nat's in Johnson City,TN, I was fortunate enough to be able to take some photos with a 35MM camera of an original paint 69 Mach 1. Here are some photos of the black out on the hood with pin stripes. These photos are 4x6 and I took them about 12-15 " away from the hood surface.
Hope this helps.
