Back in the 60's my friends and I wore decals on our vent windows and our rear quarter windows like a badge of honor. My favorites were HURST, Shift as hard as you want but don't break your arm. Moon Equipped with the big yellow (or white) eyes. Honest Charley's Speed Shop. Sun Instruments ,picture of a tach's face, and my favorite of all, the big red heart on my lower front fenders of my GTO, I Love My Hooker Headers. What was yours?
