I am just wanting to verify the details of the truck I have been working on. I found a number which was on the drivers side of the frame by the steering box. I believe it to be a 1940 1 ton with the 85 hp flathead. If anyone could tell me where I can find a good decoder I would greatly appreciate it.

 

That is the proper location for the serial number.
