I saw a 67 coronet once with the round marker li, and this person said that the Mexican 67 Coronets had them, i dont know if its true or not, could be like Bill W. said as well. I too have seen these cool side markewr lights on different year mopars, somebodies Junkyard " aha" idea. they are second only to the 71 Charger side mar`ker lights for coolness. nealk zimmerman, eugne oregon
