WTB: 64 Valiant 2Dr HT title

You restored a car with having a title?? Yikes! If it turns out to be stolen, the owner will be real happy that you fixed up his car for him. Your state should have a lien process you can go through to get title to the car but you risk losing it if the last registered owner want to pay off the lien. If you're sure the title is just lost and your dealing with reasonable people, talk to the guy you got it from and see if he'll help you get a duplicate title. If he's not the last registered owner, ask him if he knows who is and go from there.
Good Luck!
