I bought the truck with no title it has a vin number but i went to the dmv but no records of it that means that it hasent been titled for over 10 years
The process varies state to state. You'll need to find out what it is in Texas. Best bet is to ask the Texas DMV.
call these folks. As long as you have a good vin they can get you a bonded title in about two weeks. http://www.lawrenceautotitle.com/
