best guess long shot

Region 44 = Syracuse, NY

This Plymouth dealership existed in '65 & opened a Ford dealership in Albion in '79 under the same name at a different address (13931 route 31 west Albion NY) 2 miles away.

per Google Maps the (Chrysler?-)Plymouth building is still standing & the Ford dealership (& former U-HAUL) is an empty lot.
