Searching for my previously owned Barracuda

Hello everyone,
I had decided to attempt to locate a barracuda that I sold at Carlisle Chrysler show in June 1986. I asked a local police friend to run the vin number but he struggled do so considering it only had a 13 digit vin number. I sold it to a person in Mass of which I made contact, but he said he sold it 30 years ago to another person in Mass. Any suggestions? I have the vin number and build sheet as well as the fender card. I'm told there are data bases out there but I don't know how to access them. Thanks, Wildcuda
