My first Mopar A Body - '72 Dart Swinger

I found it at a salvage auction in MN recently. Previous owner had a "little" engine fire... It's running again, I have an appointment next week to get the tag and title and put it back on the road. Any ideas how to find the previous owner? My paperwork just lists the insurance company.

Thanks for adding me to the group! I've been here a hundred times already getting it running last week.
