Is my car a Tag Job? Barracuda Decode...

I also went thru the SO# vs VIN issue a few times with my State Police. They will inspect every car/truck/boat/plane that comes from out of state. If there is a VIV issue they SIEZE the vehicle right now.
They did that to a 1950 Dodge Panal van I bought in Idaho. The VIN was like 8 digits and they were saying it had to be 13 digits. It took two weeks to get my van out of jail. I had to find 4 other 1950's Dodge trucks and photo their Vin plates and the Washington State registration papers to prove my case. This took flagging down two vintage Dodge truck drivers in the city and explain why I was asking them to stop. (Yes, I always had a 110 or 126 Pocket camera in the glovebox)
Anyway, they called that 1950 plate a VIN plate, not a SO plate. Who am I to argue with, they have hand held protective devices on their hips......
