After some bouncing around off road I realized there was something I'd missed. Car 23 had it's shackles and their bushings replaced but I hadn't gotten around to replacing the inner leaf spring bushings. The 1964 Toyota Land Cruiser isn't know for it's tracking but my fj40 was getting worse. So I got under the car and here are the bushings that were removed.
There should be eight but two had completely disolved and the rest weren't far behind. Car 23 is tracking much better now.
