Welcome.

At least an Arizona truck should be fairly rust free!
We have a marketplace section where you can post a Want To Buy, or maybe find someone who is offering a door to a good home.
Please do make a new topic in the main forum if you have some specific questions about your truck, or start a build thread in the projects section so we can follow along.
