Some 14 bolts with duals are very wide, like modern dual pickup trucks.
The "cab and chassis" 14 bolt with duals as they come, or singles if you want, is just right for an AD 1 ton, or 3/4 ton for that matter. Width is nominally 62.5" same as original single and dual.
Welding is required to reposition, or better yet replace, spring pads on axle.
Then you have brake choices.
The deep dish drums that come on a C&C axle get very close to the AD rear springs, but they should fit and leave only enough room for U-bolts and very tight to reach bleeder screw.
You can swap shallow dish drums and use same backing plates and shoes as the axle comes with.
This requires welding new flanges on the axle tube for new backing plate location.
In my opinion less desirable option is aftermarket brackets for using front rotors and calipers from a 4x4 pickup. You loose parking brake, or have to purchase expensive non spectacular calipers with parking brake.
Better disc option is swapping disc with internal parking from late model 1 ton. Also requires fabrication and welding of flanges on axle.
Either rear disc option should accompany front disc brakes.
