Honestly, I completely forgot about their bar! Last fox I did, we used the stock ARB mounting points on the LCA's and made our own splined bar mounts to swap out bars of different thicknesses.
In that case, your idea would work quite well. The johnny joints are definitely nice. Have used them on a couple different things with good results. Got ours from Ballistic Fabrication. Instead of a snap ring they use a threaded retainer for the race so the joint can be tightened as it wears.
