Given the information you have provided so far, the model year of the Dart you are
describing has been narrowed down to:
1967
1967 Highlights:
Totally changed styling from the previous year, this is the
first year of the basic "1967 through 1972 shape".
Rectangular front turn signals which are positioned outboard
(they are nestled up against the headlights, and follow the contour of
the grill)
No sidemarker lights
Features unique to the 1967 Dart (as compared to all other 1967-1972 style Darts):
No sidemarker lights at all
Rectangular front turn signals which follow the contour of the grill
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, outboard turn signals which follow the contour of the
grill identify it as a 1967.
The lack of sidemarker lights provide further confirmation that it is a 1967
(The fact that it has no sidemarker lights is actually enough to
ID it as a 1967 in one step. Likewise, the fact that the turn signals
follow the contour of the grill is also enough to identify it as a
1967 in one step.)
The distinguishing feature of the 1967 Dart's front end is the turn signals,
which are rectangular in shape and are in an outboard position, almost right up against the
headlights. Notice how they actually match the curve of the grill as
they reach out to try and touch the headlights.
The rear end of the 1967 Dart is basically squared off from front to
back (it does not slope like the 1970+ models), and the tail lights are
located in the back of the quarter panels (as opposed to in the bumper
like the 1970+ models).
Notice also that there are no sidemarker lights in the fenders or
quarter panels. The 1967 Dart is the only one in this body style
to not have these lights.
