maybe I'm wrong but i think he is asking about changing a 2wd trans to a 4wd trans.
in my opinion, its not worth the work. 4wd AW4s can be had fairly easily.
so will you not be able to use regular shafts as spares now? well unless you change out hubs...
RCVs are cool, but i kinda like having a weak link being something that can be replaced quickly and having the ability to keep wheeling.
it was actually just before the last hard climb with the rock face on the right side.
the JK actually made it over the log but got about 1 foot in the air and stayed in the throttle wide open so the rear end broke when it landed.
thanks. yeah that flop was on Mason Jar. cage held up great. would have taken out the windshield without it. its definitely a good time when NAXJA is there. lots of well built rigs and some good carnage (like a supercharged LS powered JK on 40s breaking a 14 bolt shaft and detroit locker on your turn)
