That doesn't look like a factory pin stripe deal. I'm not exactly sure but I do know there was a stripe that went around the cab belt, on the wheels and I THINK on the leading edge of the grille bars.
Those stripes in the running boards and all around the fenders are suspect for sure and the photos appear to show th stripes were painted in short sections, not the way it's done... a good pin-striper will lay down a long stripe.
HERE'S what I found on mine.
