possible 1946 chevy shortbed project

[68c10owner]

A buddy of mine has this truck. Its completely taken apart and there is no frame for it, just the body. seems to be all there except the chassis. I dont know much about these trucks other than they are pretty much the same from 1941-1946. Is there parts available new for these trucks? I know the S-10 frames are popular but are the 41-46 frames hard to find? Any other frames work without too much work? Wouldnt build it into a show truck, maybe rat rod style who knows. Will definately be something we drive. Would be a father/son type with with my boy. He`s only 5yrs old but loves trucks like his daddy. I just want to know what I`m getting myself into if I bought this truck.
