The 1960-1966 Chev/GMC Factory Assembly Manual has an abundance of information regarding VIN's and their significance to the vehicle they are attached to. I bought mine from Chevy Duty (chevyduty.com), however I see them on eBay frequently for about $20-$25. This manual addresses many of these questions. I have found them to be very valuable in finding out information specific to my VIN's. I hope this helps.
