OK, I've done a few alignment too, about 35 years worth. There is no duplicate problem that has simultaneously occurred to both rear wheels, especially if you changed the springs already. I don't know where your getting your toe reading if you can't tell me the camber reading. It appears your trying to align your car with a tape measure. This isn't going to cut it. You need to come up with some specs and actual readings before you can even know if you have a problem and which wheel its in.
