Is a CKK 1114B1 Chevelle 12 bolt worth any more than any other Chevelle 12 bolt? Looks like it's a 4.10 from the 14th day of November 1970 if I decoded this correctly. No mention of Positraction and no E stamped on the tube that I can see. It does have a 4 series Eaton Posi in it, but that's easily changed.
