If it is indeed the stock axles, the front would be a Dana-25, and the rear is a Dana 23 Full Floater. Neither of these axles live very long with a V-8 spinning them. If your rear is a Dana 44 and the Jeep is a 43', the axle had to come from a 49' or newer. The D25 was used into the 60's, and the D30 came along in the early 70's as an open knuckle design. The closed knuckle D27 was used between the 25 and the 30. The 30 is about the best "near bolt-in" replacement. The back, if it is the D44, can be pretty stout with the Warn FF kit ($750-800 not including locking hubs). There is not a one piece set produced for this. But, Moser will make a custom set if you send them the two piecers for templates. If you have the 5.38 gears, the front has to be a 25 or 27 as those gears were not offered in the 30 (to the best of my knowledge). I am currently investigating the possibility of putting the 5.38 gears into a D44 front axle. I am not sure if there are any D44 front axles that will work with the 5.38 gears (axle shaft dia, and spline counts). I am going to narrow a full size axle, and probably cut new splines in the shafts to match the 5.38 carrier (if both sides have to be narrowed). I hope this info helps.
