yes, '69 has the same kind of code
mine is 2 AN 10 31 68 W

The Chevrolet by the Numbers and Corvette by the
Numbers both have it wrong as far as date codes.

This looks like a julian date code, but may also
be Feb '65?? (2 65).
Except the casting date makes no sense either
as it looks like I 10 8 which would be Sept 10, 1968.


Sorry RPOZ4Z, I just can't figure it out any more...

Update:

I did the "spin the tire count the revolutions" trick, It looks like it's a 3:70 ratio.
