On my 59, which is original cab and frame, the number on the drivers cab hinge jamb is also stamped on the top of the frame next to the steering box and under the cab on the drivers side. At one time I was going to put on another cab, in Idaho you take the finished truck down to DMV and they decide, usually it is the number on the frame, and they install a new tag on the door jamb with the same number. If all numbers are gone, they assign a VIN and issue a new tag like it was a hot rod. It is licensed to the year of the sheetmetal so you can have say a 59 on a tube chassis with new suspension, LT1 engine, etc. and it will still be a titled as a 59.
