CJ5 running gear to a CJ7 frame and body

Hi guys, I saw the artcile on the CJ to YJ swap, which leads me to ask you this question:

I got a bud who has excellent CJ5 running gear but the frame and body is toast. What would be involved with putting the 5 running gear(motor, tranny and front and rear diffs) in a donor 7 frame and body?

Thanks, Bill
