David, I pulled this picture from your post on P1. I'm sure it's been measured before and noted, but could you do me a favor and measure the distance from the outside edge of the 1/4" stripe to the very edge of the hood at the windshield and just where the curve starts. ON BOTH SIDES
I'm curious because I have it at 6" and that was from other info I found. Perhaps that was in the Mustang Monthly article, I can't remember.
Also, as noted on the 429 megasite, the "expert" Bob Perkins notes that the black-out paint is NON textured PPG 9423. That's interesting because from the scan of an actual original PPG color chart for 1971 & 72 Mustang (and others) the black-out paint is Ditzler/PPG 9381. I could not find reference to the 9423 anywhere on those charts, back or front. My local PPG supplier tells me he can still match 9381.
See below. I posted the 72 as jpaz has a 72 Q code.
