Bill,
I tried Jolly's site and went back using your link (it worked better than my web search). This site does a great job of identifying trucks up to 11,000 lbs. GVW. My model 5500 medium duty truck has a GVW of over 19,000 lbs., the model isn't included, and the VIN sequence is different. I am hoping someone knows more about VINs for the mid-1960's medium duty trucks that seem to fall between information available for light duty trucks, older trucks, and the establishment of standardized VINs.
