OK, tomorrow I'll adjust camber on the one wheel that is out (easy). I'll also crawl under the car and see if an idea I have for setting rear toe and thrust angle will work. If so, it should be relatively easy. The jack stands and string idea would work, but you have to get the car precisely centered. If my idea works I can easily make a jig that I can reuse if needed. I'll design it to work front and rear and so that I can use it with the car on ramps so that I can adjust and measure without moving the car. I may be a it ambitious, but it could be a fun project (or not).
