The fact that it is in primer will drop down the value quite a bit. A good running, straight truck in primer will proably bring 2-3 thousand, depending on how nice the interior is, how good the body work is, ect. Selling it as a box of parts won't bring much either. If it were mine, i would put it toghether, and give it a decent coat of paint before i sold it. Then, you can get 4 thousand or more out of it, depending on how good of a job you do. Beware, you may find it impossible to part with the truck after you put it togheter and paint it, and see how good it looks
