A good buy or should I just forget it?

Hey all, coming here for some 60-66 advice.

A guy in the neighborhood is selling a 60-66 K/20 plow truck he has had for 30 years. 4 speed, 283 from a chevelle he rebuilt when he got the truck. I haven't seen it leave the yard in 15 years. I've always wanted it, and its been sitting unused since he got a "newer" plow truck last year. This morning it moved from his backyard to the side of the road with a for sale sign.

$800

There isn't much sheet metal left. Cab floors are rotted bad. Core support is barely there. Doors are crushed badly, altho they open and close without issue. Frame is solid, as well as the flatbed on the back. The old knobby snow tires hold air, and I believe it still runs.

I want a funky old plow/yard truck, but not if it crumbles in on me when I'm using it! It won't see the road as I have my 86 C10 for hauling. Is it worth it?
