Found '76 Dart Sport - what are these holes?

$1500 for that with no motor is too much. Try offering $500. The stripe is not factory to that car but looks like a later Duster stripe painted on. The seats look to be out of an 89 or 90 Omni. The holes???? Maybe one of those 70's alarm systems, although I have never seen more than one fender with a hole for one of them. The advantage of that car for you is that it probably has disk brakes and the spool mount k-frame means readily available motor mounts for the engine swap of your choice.
