Finally, I have added some before pictures to the original post.
Thanks for the comments, y'all. Your input helps more than you know. I've gotten a few raised eyebrows about the fourlink plan and want to justify it. Rear springovers need trac bars or pinion breakage is inevitable on a heavy truck. A trac bar forces the leaf to act as the lower link and in ends up in compression and after a few hard trips (like the Rubicon) you wind up having to swap leafs. I know somebody will jump in and tell me how their truck has done lots of wheeling and never broke a pinion or turned the leafs s shaped but I'd be surprised if they also told me the rig weighed more than 3 tons. With all that in mind I watched as my shopmate, Shaker, built and then rebuilt his 4link to make it work flawlessly. The pinion is always at the designed angle, the antisquat is calculated, the bags allow full performance through the entire load range. The Rubicon Express ends are field servicable, widely available and severe use proven. The added bonus is that it can be used for leveling when you are camping on the roof
A reliable air sytem is a design requirement for this rig and as a result I feel less concerned about air actuation of the lockers even though I've never had any luck with air lockers.
This truck, thankfully, came with a few upgrades. The solar converter is already there (I'll have to modify the wiring to the latest Stone version) and it has boost and pyro guages already installed.
The following pics show two rigs I have spent a lot of time with and you can see the 4link working perfectly and the s/o crying out for mercy. To the credit of the leafs, they are still working today though somewhat curved.
