Dana 44 from 69 International PU

Found front and rear both for cheap. Would these work on an XJ? How much mod would be required?
TIA

ok these axles are drums front and rear first off, second off sprung under, third they are tapered axles, and not worth buying. have you ever owned an old scout? everything will be welded togethe from rust. the front in my opinion isnt worth using. maybe the rear if he wants like 25$ and it has brand new brakes and a newly rebuilt factory power lok . those old scout brake parts are expensive...

I thought that but wanted to be sure.
