Worth of 68 4x4?

[The Blue Pig]

Hey, this guy I know has a 68 half-ton 4 wheel drive, no rust. Frame has no rust, body (including rockers and corners) has no rust, and there are a couple dings in the bed and aother areas. I really would like to get my hands on it, he said it belonged to the local dealership, they drove it around until 70 or something then it was in a flood. They sold it for cheap. He said he drove it into the space where it sits. Windshield is butsted out, but I had one of those done in my 69 for a couple hundred bucks. The truck has like 50000 orig. miles on it, what do you guys think this thing should sell for? He said it has the old "ball-type" front end, I didnt get a chance to look. Is that a descent front end? Any opinions or advice would help, I think he wants at least 4 grand for it, that doesnt seem too out of range for that truck. He knows what he's got...Damn! Oh yeah, truck is a longbed too.
