And, NO pre-1970 U.S. vehicle has a VIN number...
Prior to the VIN system, we just used "serial numbers"....
It's worth making the distinction...
When someone in a motor vehicle administration hears "VIN Number", they start expecting the long alpha-numeric code that's found on the plate rivetted to the dashboard, at the lower-left of the windshield....it don't exist on pre-1970 vehicles. Period.
Good luck with your search, Magilla...
Hope you get it squared-away !
