70 Duster missing title

A friend of mine has a 1970 Duster that he recently picked up from a guy who was going to turn it into a race car. It has no title. He did some investigating and the car was written off as totaled by the insurance company. Supposedly they won't release the title because of the salvage lien or something. Is there anything he can do? He wants to save the car because the body is really clean on it. Any advice may just save another classic Mopar from the scrapper. Thanks!
