Scott,
As the above poster was saying, I too took apart a real early built shaker (9-69) and it had 2 pin emblems in it (though it was drilled for three). It was an orig paint bubble, but whats the story on the emblems? Possible supply issue with the 3 pin ones and they threw on some 2 pin emblems instead? After all 2 pins are very commonplace but finding the real 3 pins is tough!
