New member 67 GMC SB wideside 4x4

[arcticman]

Hello everyone,
I'm new to this site. I'm just in the process of purchasing 67 GMC 1/2 ton short bed fleetside 4x4.I've started to research the truck and it is checking out to be a true original unmolested survivor. I've decoded the Vin. # using a decoder built on this site and it matches the trucks current set-up and also matches the build sheet in the seat back coils right down to the original paint, optional v6, and the wood bed. I was trying to research production #s and the site I came across said 1046 units built in 1967. My question is this;
1) is that #a combined total of both Chevy and GMC trucks built.
2) if its a combination of both does anybody know the breakdown of that number how many are Chevrolet versus GMC Trucks.
3)The truck is a manual 4 speed with locking front hubs that look to be original Is their anywhere I could find pictures of original locking 1/2 ton hubs?
4) Is their a VIN # stamped in the frame if so where would it be located?
Thanks for any help you can provide.
