Car origins

Anyone know of a way to find out what dealership got a car or where it was sold? Without having paperwork or original owner I bought 2 dusters near Winston Salem NC and I am working hard on getting the car into good shape. But have recently became curious in the history of the car.
Someone broke the striker for the door latch. They installed a latch used for a pad lock on the inside of the car. The latch was gone but I left the holes just because I felt the deserved to be there just because it was part of the cars history.
