He has a coil spring rear end, so he has to find a 6 lug coil spring 14b donor

6.2 SUVs, and most NNBS Escalades will have what the OP needs. There were certain options and codes that led to the Avy getting it too, but I don't recall all the details

With factory autotrac you get steel driveshafts and stronger u joints, no need to change them out like the aluminum shafts...

My '14 6.2 Denali with AWD didn't get a 14-bolt but my 6.0 4wd Avalanche did. So maybe hunt a 2wd 6.2 suv. I think the Vortec Max trucks got them as well and anything with max trailering package.

There were no Vortec Max SUVs. I dont know the config of your 14, but it probably had that hybrid "12 bolt" thing

He doesnt have rear leafs. Anything with rear leafs isnt a bolt in, but the axles are essentially the same; save for the brackets welded to the tubes
