Just to toss my two cents in for Nevada... I just took my 62 C10 down to the DMV for what I thought I would need. Which is a VIN inspection, since I had to do a VIN inspection with my 63 C10. After I got there, I discovered that no VIN inspection required on my 62 since it already has a Nevada title that has been signed over to me. My 63 had a California title. So it required a VIN inspection. The frame VIN is stamped into the frame right above the front crossmember on the drivers side. Just lateral of where the motor mount would be or where the motor mount perch sits.
The reason I was concerned about my 62 is because the cab VIN tag is gone. The PO claimed that it had "fallen off"..... Now we all know that is BULL****.. they don't just fall off.... the rivets have to be drilled out. In my case, I think the previous previous owner... wanted a keepsake.. Didn't matter, since the frame matches the title. When I took it to the DMV today, they looked at the title.... told me that as long as the frame matches the title, I am good to go...
Here is my 62
