If everything is on the up and up, you can use Broadwaytitle.com in Birmingham, Alabama. Vehicles built prior to 1974 don't have titles in Alabama. Broadway title is basically a car dealership that will give you a bill of sale based on your VIN. In most states, a Bill of sale from a liscensed dealer is all you need to register it. This bill of sale basically says you bought the truck from this dealer in Alabama, therefor being older than 1974, no title. Hope this helps.
