Chevy, There is more than one set of numbers on your frame. If you found the numbers on the side of the frame they won't match anything. If you find the numbers on the top of the frame they will partially match the vin.
But I see a big red flag here. If the cab has NO vin plate then DON'T buy that truck. As said in post #3 it won't be legal. If you don't have a vin plate on the cab, then you don't have a truck (Except for parts) The vin plate is on the drivers side rear pillar under the striker.
