"The seller" Sorry I missed that. This is a truck your looking at, to buy. My bad. Can you ask the seller for a better SPID pic. One that includes the top and bottom and hopefully shows the clear film cover. I would also like to see the way the vin is printed. Just trying to cover all the bases.
VIN locations are where you stated.. Top of frame rail by PS pump and top of same rail between the cab mounts.. VINs are not stamped into the sheet metal of the cab, on our trucks.
