How do check for liens against cars in PA

Hello PA Mopar fans, I’m looking at a 73 A-body that is in pretty nice condition and I want to make sure there are no liens or other outstanding issues with the car. Is there a one stop shop/organization in PA that I may be able to accomplish this task? I would hate to spend that kind of money only to find out someone is going to take the car because I failed to do my homework.
