Export car 69 Dart GT

It looks like it does not have headrests. Headrests, were an option, until January 1st, 1969, when they became standard equipment.

Yep. My '69 GTS was built in early October '68 and doesn't have headrests. It does have the optional shoulder belts though. It also has factory AC (that works) which was a full 10% of the price of the car back then.
