The Stovebolt Site Forums The Shop Area General Truck Talk numbers on frame?

The Louisiana State policeman in charge of inspecting old vehicles and street rods told me there was a number on the outside frame rail beneath the driver's door on all AD trucks. I can't find the number. Can anyone shed any light? Thanks Ralph

GM did not start stamping VIN numbers in the frame till 1955.

AD trucks do not have a number on the frame, the TF trucks were the first to have numbers on the frame.

Thanks guys. I sure couldn't find one

Unless it is a pre MAY 1949 GMC or a post post 1955 first series they did not stamp identification numbers on the frame.

There is one exception, if the body is a FC (FORWARD CONTROL) it will be stamped on the frame.

We can tell you lot's of things you can do, but there are legal issues to deal with and you don't want to get caught by the Police or DMV for modifying your truck VIN's. The best thing is to be prepared with the information from your shop manual.

Here is some of that information that shows what these tags were used for and not for registering them as VINS as we know of them today. MORE INFO 1954 SHOP MANUAL
