You have to think of a "traction bar" less as a LCA attachment, and more as the triangular LCA. If you build it right, the lower ball joint will only move in as much as it's inner mounting bolt allows it to (how unparallel it is to the car's centerline). The LCA & inner bushing will not bind a bit. You'd also need no heim joint where it attaches to the LCA. To do it right, you need to put the traction bar's chassis mount point DIRECTLY in line with the pivot of the LCA's inboard bolt.
That one looks alright, since I can't see it well, nor have I been around an EF in a while.
