Positive camber on rear wheels after installing spring relo kit and SS springs

You need to explain what you are seeing better. The only way to cause toe in on a solid axle is if you bent the housing, which I doubt.
If 1 side in pointing inward (at the front of the tire) the other side should be pointing outward. As already stated this is called thrust angle not toe.
Measure wheel base on both sides of the car and compare it.
