I found a '69 Z11 n Epay today which is a mere 65 vin units before mine. It purports to be a one owner car. My car is 9N626575 and the Ebay one is 9N626510. Both are 03E cars. My fisher body number is 304192 while the Ebay one is 305271 or 1079 units higher. Is there an explanation for the fact that the VIN indicates they were probably made on the same day but the body numbers were 1079 units apart?
