FAT cab 12 frame serial no location.

[rob love]

This body has a body number in the location you describe, and the serial plate is missing. The museum is being offered a set of plates that may be original to this truck, but I am trying to determine that the plates offered are in fact for this particular vehicle.

I will look at the engine serial number to compare, but of course engines get changed after 70 years. But generally frames do not, which is why I am looking for the frame serial (if it exists). I have observed serial numbers under the door on Ford Cab11 trucks, and forward of the right rear spring hanger on Ford cab 13s. But I did not find numbers in either location on this cab 12.
