Depends,What Year?
On the 40,s the VIN was on a plate on the Pass. side cowl and only readable when the hood was opened.
The Advance Design trucks starting about mid yr 47 thru mid yr 55 were on the drivers side door post between hinge pockets
Likewise the Task Force trucks that followed thru 59.
The 60/66 and 67/72s varied between the door pillar and the windshield pillar and Ive even seen some on the roof pillar, BUT all on the Drivers side.
Sorry for the Ramble but......... :p
