Found '76 Dart Sport - what are these holes?

The holes are on both sides of the front fenders....so two alarms, one for each side of the car? I don't know about that...

I think I'm now convinced they were for some add on mirrors, deer whistles, turn signal lights (but the wiring isn't cut) or whip antennas. The car has a major trailer hitch and low rear gear, suggesting highway travel.

Thanks everyone! I might post some more pics of this car in a new thread, if anyone's interested. We're just cleaning it up now and figuring out what needs to be done to make it road worthy....it's great fun! There's fuzzy fake fur glued everywhere and even an 8-track player in the dash! Was in a barn since 1990.
