Russ correct no VIN on 68 or earlier in the hidden codes. They used the year, factory, SPD and SO Number on the stamping. There are only two ways to tie it together to the car.
Broadcast sheet, or for 67 and earlier you can get the build card from Chrysler Historical and it will have both numbers on it. For 68 you can be screwed without the broadcast sheet since you cannot get the build card for them..
