Have title/No 69 dart.

Hello fellow A body fans. I'm a newbie on this site, but not to the Mopar world. I've owned a dozen or more b bodies, but I'm trying to figure out a strategy to acquire a 69 dart.

I've posted in lost and found already, I'm looking for a 69 Dart 340 car VIN: LM23P9B187902

This car was originally bought new by a family friend in 1969. He learned of my Mopar obsession, and gave me the title to his long lost car. At any rate, I've exhausted my resources to locate the car. (last seen just a couple years ago near Madison Wisconsin)

My question: Can I buy another car....title or not and convert the tags to make a legit 69 340 4-speed car? Is this even legal?

If not...is there any value to this title I have at all????

Any opinions, insight or related experience would be greatly appreciated.

Thank you.
