Hot Rod john,
I received replies from the GMC 60-66 guys that GMC did not stamp the VIN on the frame as Chevy did and I'm probably seeing a part#. Since I can find no other number, it verifies that my chassis is GMC. I must have a big truck gauge cluster as my VIN plate shows it as a 1/2 ton cab.
Well, now I know what I've got, thanks.
