The Trade

I have a closed cab conversion 1946 WC6 with no motor or trans or interior and all bad glass and a crushed driver door. However it is a beastly old army truck. I have a friend who has been trying to get it from me for close to ten years now, and has offered me a trade the whole time. He's got a '69 Polara 4 door and a '69 Polara 2 door and says he'll give me both straight up. Neither run and the interior is shot in both but the body's are in decent shape. What should I do?
