I'm sure all the dies are missing. Dies have a limited number of stampings they can do depending on how much they stretch the metal. The more they have to stretch the metal the more force has to be applied to the dies. Where the metal slides on the die it slowly wears the die away. Thus creases become softer and radii become larger. Once GM (or its supplier) was done with a die they were usually sent outside of the states for use. One of the reasons that the foreign models have different panels as the panel die for that area may have been bad or the piece next to it was no longer coming out of the die correctly. Dies are made of large heavy steel pieces and have a good scrap value so often they were scrapped as they had no immediate value to the company.
