Given the information you have provided so far, the model year of the Dart you are
describing has been narrowed down to:
1968
1968 Highlights:
Round front turn signals which have been moved slightly
inboard (away from the headlights)
Round sidemarker lights in the fenders and quarter
panels
Features unique to the 1968 Dart (as compared to all other 1967-1972 style Darts):
Round turn signals
Round sidemarker lights
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 round, inboard turn signals identify it as a 1968
The round sidemarker lights provide further confirmation that
it is a 1968
(The fact that it has round turn signals is actually enough
to ID it as a 1968 in one step. Likewise, the fact that it has round sidemarker lights is
also enough to ID it as a 1968 in one step.)
1968 saw the addition of sidemarker
lights in the fenders and quarter panels. These sidemarker lights are
round and are located high on the body, a little higher than midway up
the car. Also, the front turn signals were moved inboard a bit (away
from the headlights) and were changed to a round shape instead of
rectangular.
