GM part # 2551622 - Item that I bought back in the mid 1990's when I had my '84 GN. It has been sitting in my drawer in the factory plastic with the original tape/adhesive. There is some green oxidation on the edges that can be scraped off. There is one spot where the chrome came off. $85 shipped to your door. LMK if you have any questions or need further pictures. I tried to take as many detailed pictures as I could.
