If I'm not mistaken, in the old 359 kit the compressor is belt driven off of the rear accessory drive. I don't think that I would change any of that. The simplest conversion would be to get the manifolds, pipes, turbo set up and probably blower out of the AMT Aerodyne cab KW. The reissued Papa Truck would be a good source. If you can't source those parts, you would have to scratch build them. Scratch building the manifolds may prove a little tricky. I've never personally converted one exactly this way, but it shouldn't be much trouble. I've made a homemade rear turbo set up on one, but you won't have room for that.
Hope this helps,
Brian
