This thread got me curious, so I called up the dealership that took over the place that the previous owner bought my truck at in 1980. They were awesome enough to send me a digital copy of the old dealership’s decal they put on the trucks they sold. They even had a 70 c10 they had originally sold in the service department the day I called, so the manager sent me some pics of that one, too, as a reference. I took a little paint thinner and tried to patina the sticker a little to match the rest of the truck.
