54 Chevy Frame Swap options

[Malibu Monte]

I have an oppurtunity to purchase a 54 Chevy 1.5 ton or 2 ton truck. The truck is an ex grain truck that belongs to a co workers cousin. The cab and fenders are in excellent shape with great patina, but there is of course no bed. I have thought of some options for a frame, but don't really know what will work. I have some nova subframes laying around both front steer and rear steer that I could use. I also have a 2000ish S10 blazer 2dr 4wd that I am leaning towards using if it will would work. the wheelbase of it is 100" inches even (center to center). The blazer has a good 4.3 and overdrive tranny and working 4wd That would be nice. Has anyone ever done this swap? is it doable? What do you all recomend I do? and lastly how easy is it to come across beds for these and what years will work?
Thanks,
Monte
