The bottom right 8 digits on the fender tag match the last 8 on the radiator support stamping (scheduled production date mm/y space shipping order number).
The 2 digits before that match the 6th and 7th on the VIN tag(year and mfg plant).
On the bottom left, the 1st four characters match the first 4 on the VIN tag (car line, price class, body type)
On a 67? I though only way to match fender tag with the SO number to the body was with broadcast sheet or window sticker. I also thought 67 was similar to 68 in that regard.
