I recently inherited a 1956 Mercury Monterey from a family member.  Long story short, it's been passed around the family for the past few decades, never really driven much, no one is certain where or even what state the title was last issued in.
I live in Kansas, bill of sale only on antique vehicles is fine here, however, if no title is available they have to do a VIN inspection.  Been awhile since I did this, but last I remember one of the requirements is that they have to be able to find the same VIN stamped in the vehicle in TWO separate places or they issue it as a salvage/rebuilt title.  The car is original, so I'd rather have a clean title.
Plate on the door is easy enough to find, but what other location can I find a serial# that matches the door plate?
