I have that pic as part of the advertisements for the 71 demon 340 that went out in magazines in 70 Warren, i think that is whats known as a "pilot" car if you look close at the pic the side stripe doesn't come to a point at the fender ext, also it looks like the stripe was Photo shoped on, also not seen in the pic, is the demon sticker which was doctored on for the mag spread. i too think the line should be closer to 1/8".
