you will want the axles from a 75-79 wagoneer or cherokee. the drive shaft is on the passenger side like your cj5. they are only a couple incjes wider. get the rear one also it a dana44 and it'll match the 6 lug pattern. the 80 and up ones drivers side ones and they are wider yet like a full size chevy
if you use just the front you'll have to steal the rotors and hub from a 79 bronco to keep your 5 lug.
