When I get a little time to dig through my books I'll see if I can turn up the WB information.
Otherwise the above list looks spot on.
Caveat though... GM for some reason changed the VIN throughout the 60s on the bigger trucks, to my knowledge 5500s and bigger. Most will decode just fine, like the above was, but others will have letters that make no sense. I have a few brochures that have some data for larger trucks.
The 4000 are technically classes with the pickups as the factory manuals are 1000-5000 series. Most will use the same nomenclature.
