Not all states even have titles for vehicles older than 1973 (NY For example, when I sold my 69 Roadrunner since I never registered it all i could give was a bill of sale). Do you have a bill of sale of some sort from the owner to you?
Check out the last post in this thread, guy is from texas says that state is pretty easy about just giving you one:
