Two years is achievable. I will follow through with a SAS for the X. The wheelbase is perfect, comfortable,stout,and isn't the every day Jeep that everyone has.
My plan as of this time is:
Front: Early Bronco D44 with Chevy knuckles (6 lug) 4:88 R&P.OX locker, Coil spring/radius arm

Rear: Stock housing, 4:875 R&P, ARB air locker. Spring over conversion.
This of course is all easier on paper than the real world
