I've had these for years in a box and dug em out today. The ones on the left, the short ones, are for a Cuda because they came off my old 71. I put them there for comparison. What are the right side pins off of? They appear to be stainless and have washers similar to standard hood pins, not the large toothed style like on the Cuda pins. These 4 pins came extra with my 71 Cuda that had factory louvers. Anybody know if they are something special or just something somebody made in the 80's???
