VIN stamping question

[Nevada51]

Thanks for the prompt responses. Seems a partial number is it and nobody understands the quirks of old vehicles these days.

The lady flat out refused to register it as it didn't match the title paperwork 100% which I get, but it is pretty clear that it is original. Somewhat bizarrely she tells me I can stamp the number on there myself and that will be fine, as long as it matches! Go figure, bureaucracy gone wild.. I think I will have to go this route which is annoying given the truck is so original.

FWIW I also found this link (below) and the number is also on the driver side rail under the cab. I can see it there too and it is only the partial number. Odd that the factory stamped the frame in two spots, but I guess there was a method to this back in the day.
