I have what I believe to be the rarest 12 bolt rear end. I am going to post the number code in a picture so you know I am not making this up. Please decode this and tell me what you come up with. The code on the drivers side front is GA0119B casting number 3859140N and the date is L214 (December 21, 1964). It also has the larger 11 inch drum brakes. I look forward to your responses. Todd
