Found a truck today, what is it worth????

[Graham57a]

Okay so my buddy told me about a truck he saw that was the same body style as mine for sale on his way to work the other day. We drove out to the place today and the guy was outside so we stopped and checked it out. The truck is a VERY clean and original lwb 1/2 ton 72 chevy. It's hugger orange with a white roof, cheyenne package, A/C, 350-350 clean. Turned it on and it purrs like a cat. AC blows cold, everything is extremely nice and original. The tailgate is straight, still has the band on it with all of the letters. The old man who is selling it is the second owner, bought it from a guy he goes to church with about ten years ago. The inner and outer rockers and flawless, the drivers cab corner has a little bit of surface rust, and one of the cab supports has cancer on the very bottom. Other then that, I would consider this a rust free truck. The original wheels and hub caps are all there and extremely nice. The guy had every registration receipt since 1972. Just curious what you guys thought the value of a truck like this might run. I was thinking maybe 7-8 grand??????
