The sheets referred to are the 'Monthly Vehicles Shipped Reports.' The vehicles are shown in the order they were produced with every piece of info listed including VINS and key codes. Initially, GM Canada included the entire sheet that had your car on it with the documentation package. I have one sheet with 55 1966 Chevy II's on it, including 11 L79's. They stopped sending these sheets in the mid 90's when cloning became fashionable.
