NJ Lost Title

A friend of mine gave a 68 camaro that he bought a few years ago as a parts car for his camaro project. He sold his project and the other was just sitting. He knows I am into cars too and asked if I wanted it. I checked the vin to make sure that it wasn't stolen and it's good. Unfortunately he has had it so long that I don't the think person who it is registered under has the title.
