Need info on Duster

Thanks for the info! I'm really excited about this one. I've done plenty of trucks but this will be my first car. It has a lot of surface rust but not too many rust holes. Picked it up from a guy who's had the car sitting around since 1982. The car was barely driven and I'm the third owner, his friend being the first bought it new in 1973.

Under hood pictures!!!! Origional drivetrain or any engine???
