Chassis Identification

Here is a 67 I have and how it connects together.

In this case the fender tag shows C12 02672, C12 = December 12 1966 build date, and the rest of the SO number connects.
The body number is 72C1202672. 7= 1967 model year, 2 = Hamtramck factory, C12 Dec 12 rest is the SO number

Certicard does have VIN BH23E72xxxxxx
the trim is same H6V, and paint is same WW1, 5 on fender tag and T5 on certicard = auto trans, AX-4 on tag and SA on certi = standard axle and finally C12 on fender tag and the I2I2 they used I instead of 1 or C on certicards = December 12th again.

Fender tag dates used are, 1-9 is Jan through Sept and A-B-C for Oct through Dec. So 219 is feb 19th, A10 Oct 10 and so on.

I hope this helps?
