dana 70 closed knuckle front axle

[mutt truck]

So my question is can u take a 70 closed knuckle shafts and replace them with 60 u joint shafts?
Everything that I can look up as far a specs tell me that as long as the splines on the inners are the same that it should work, but I am not sure about the clearance of the u joint where the ball and socket goes if there will be enough room?     Wondering if anyone has done or knows of someone that may have done this. Thanks

Not sure about the splines on the inner but my buddie has a couple Dana 70's and he has the u joint style shafts in them
