Disk brakes off a 75 Scout II Dana 30

no they won't and if I read right the spline count it wrong anyway.

 

No they won't but I have seen some people hone the ears out and clearance the yoke slightly for the larger joints. I don't recommend this as I feel it weakens the yoke of the 30 shafts too much, but it is do-able. The advantage to the Scout 2 stubs is one can get aftermarket inner shafts and use the Scout 2 outer shafts. The other advantage is if one decides to upgrade to a 44 front housing and axle shafts down the road you can use the Scout 2 stub axles and use the Jeep/Scout 2 brakes with the Jeep knuckles. Or sell them to someone doing a similar conversion...
