I haven't been involved personally with a power steering conversion on a stovebolt, so anything I say about it will be a SWAG, with no real hands-on experience. The ones I've seen that mount the steering gear outboard of the frame seem to be pretty Mickey Mouse, with a lot of room for problems due to the oddball geometry involved. The most effective PS conversion seems to be a Toyota Land Cruiser box that mounts very close to the original position, but I'm not really sure how that will work with your Caddy engine. I'm going to assume you're planning to keep the straight axle, right? Good on ya!
