How do I get a title for a 71 truck ?

[RShaips]

I am about to buy a 1971 Chevy 1/2 ton LB 2Wd truck that has 64,000 original miles from a guy but he has no title. The owner died and he bought it after it sat for 10 years now it has been sitting for 10 more and I want it. The truck has not been licensed for 20 years. If I can't get a title its not worth the hassle. Even though it is a 350, ps, pb, air, tilt, running truck! Anybody know of a title service I can contact? Missouri DMV is a real pain to deal with. I know that some states didn't even title vehicles until the mid 70's and sometimes you can sell the truck to them and buy it back and obtain a title that way. Any help would be appreciated. Thanks
