Just like Gray Market vehicles brought into the United States, which require inspection and vin verification, some being issued a riveted aluminum tag I have seen this done in Germany as well. So many of the Ford vins were weak stampings and by the time the engine compartment is primed and painted, it can be difficult to read the vin. Of course we all know that many have the battery side apron replaced because the battery rust them out. Many are rusted out at the top corner of the overlap, even those that were relegated to arid climates. Being this is before '67. there should be three locations for the vin, if memory serves me correctly.
Left and right front aprons, right side under the fender, and the rear apron under the top edge of the fender.
