Howdy Ron Why not start out with a lift kit and some 33" tires and change the gearing to 4:11/4:56? You should be able to get waaaay up the mountain with those changes..
THEN after you see what it MAY be that your rig won't do make futher changes.
The spring over is considered radical for most jeepers.. It would be a last resort for extreme climbing for most.
The rig I have outlined with some good mudgrips would carry you a long way into the wilderness.
