Your best bet is to go to the license bureau and ask them what you need to do.
Don't know if the requirements have changed, but I went through it about 12-15 years ago--twice.
What I had to do at that time was submit pictures of all 4 sides of the truck, plus get notarized statements from several people (I think 4) verifying the truck's history, who had owned it, etc. (On one of mine, the PO was deceased, and the other one was bought from a guy who had bought it from a junkyard.)
I also had to get a bond, which my insurance agent took care of.
After all that, I was able to get titles for the trucks.
As I mentioned, this as a long time ago. Best to just go ask them what the current requirements are.
