Given the information you have provided so far, the model year of the Dart you are
describing has been narrowed down to:
1969
1969 Highlights:
Turn signals still inboard, but rectangular instead of round
Sidemarker lights moved lower on body and are rectangular instead of
round
Features unique to the 1969 Dart (as compared to all other 1967-1972 style Darts):
None
Identification Process:
The recessed front grill and squared off rear end with tail
lights mounted in the quarter panels narrows it down to 1967-1969
The rectangular, inboard turn signals identify it as a
1969
The rectangular sidemarker lights provide further confirmation
that it is a 1969
Ironically, the two main changes that marked the switch from 1967 to
1968 (turn signals and side marker lights) are also the major players
in the transformation from 1968 to 1969. If 1968 was the year that made
the Dart's world "go round", then 1969 must be the year that it became
"hip to be square", because both the turn signals and the sidemarker lights
changed from round to rectangular.
The 1969 rectangular turn signals are still different from the 1967's
rectangular turn signals though, because although the shape changed
back to rectangular, they stayed in the same basic position as the
1968 turn signals (inboard). Note that they are further away from the
headlights than the 1967 turn signals are, and they do not follow the
contour of the grill like the 1967 turn signals do.
As far as the sidemarker lights in the fenders and quarter panels are
concerned, besides changing shape from round to rectangular, they were
moved much lower on the body.
