It should be on the right side of the cab/cowl under the hood, about 1/3 of the way from the top, on the side of the cowl, not the firewall side. Look for two small holes staggered as they drilled the VIN plate in opposite corners. It should be about 2x3 inch or slightly less. There are no other numbers on the truck so don't bother looking. Also, the VIN number used the original engine serial number, so if the engine has been changed, the VIN wouldn't match up anyway. JOE
