I think the axles are Dana 27 front, and Dana 53 rear. At least I that what I'm told my 57 Willys pickup has.
It's also my understanding there isn't much aftermarket support for these axles. I trust the 2 people that told me .
There are lots better options for a CJ.
On Edit I see a Dana 24 is a transfer case. So I don't have a clue. My truck has a Dana 18 TC. That was the stock case I believe, can't imagine the wagon would be different.
The quick search I did on Google showed the 24 used in late 50's (59) and 60's Ford trucks.
