Rich, My car had the emblem on the left side of the deck lid. I always wondered why... after looking closely at the inside of the lid, I noticed a couple of holes that did not match up to the emblem pins. Closer inspection revealed that the holes were actually there for the emblem/logo of the original selling dealer. When the car was DX'd (dealer exchanged) to the final selling dealer, rather than weld the holes shut & re-paint the deck lid, they removed it and covered the holes with a "PLYMOUTH" emblem! I guess the final selling dealer's emblem was not big enough to cover the holes, so they just used a Plymouth emblem instead! It's funny how back then not all dealer emblems were stick-on affairs. Many were installed similar to factory emblems with studs and speed nuts. I agree that the other holes in your picture suggest that it had a trim panel, thus not a Road Runner deck lid. The stick-on emblem is interesting, though. I thought they all were the stud type? Maybe the trim holes were added to a replacement Belvedere/Runner lid and they (body shop or whomever) only had an emblem with broken pins and decided to glue it on?
