Well, I think I have an answer for you. Assuming that the engine will run, big if. Look at what needs replacing, re-doing or what ever. Cost of paint job if you are not going to do it yourself. Get you a book (LMC) is fine and just jot down the parts that you know you are going to need. Do some figuring, it won't be right because something else always comes up. This will give you an idea of what YOU are going to have to put in the truck. Now to answer your question, the truck is worth what you are willing to pay for it. I don't think anyone can say how much you should pay for it. All I can say is you can go to Hemming Motor News and get a good idea what a finished truck sells for, $25,000.00 and up. So weigh your options and go from there. I hope I haven't been to long with this answer. Good luck.
