If you’re not up to it, find a local woodworking hobbyist or hobbyist group. It is the number one hobby in the world so they are just about everywhere. There are some out there that would love to take on a project like that. Quite a few will like old trucks. Some are retired with time on their hands.
Media blast all the metal and paint, replace the hardware that is no longer up to the task.
Whether it is a factory or aftermarket bed, take a lot of pictures... and then take some more.
Great looking truck!
