after market ID plate You could stamp the vin # from your reg/and title on that plate and place in drivers door jam.
As stated above no paint or engine info is on the plate.
On my 50 the door jam s/n is my vin. Other states used engine numbers.
door post id plate If you had your original s/n you could get some history on your truck. I know my truck was built in Oakland California In January of 1950
