Change a '64 Valiant to '65

They're similar, however:

Different trim spears
Different folds/lines on the front fenders+grille
Cable-column auto gear shift instead of pushbuttons on '64
Different cluster and dash-entirely different
Different trunk deck (lower on '64)
Tail light bezels+lenses cannot interchange.
'65 uses bottle windshield washer, '64 has bag washer, if so equipped.
AC is usually integral to the heater on the '65, on the '64 it is usually dealer-installed and a separate unit.
Wiper arms on '64 are secured with acorn nuts, on the '65 they are press-fit.
