Darrell,
I went through the same thing years ago and I think I understand your difficulty. The problem is that there are three different brackets for mounting the lower arms (wishbones). They allow the pinion angle to be higher to match the transmission angle. I believe that they come in 12 degree, 6 degree and zero degree. It sounds like you may have different bracket angles on the left side and the right side. So, the arm is not swinging up perpendicular to the ground. This causes all kinds of geometery issues.
I think the solution is, you need to replace your "fulcrum shaft mounts" with two zero degree parts. See this diagram:

You did not mention the manufacturer of your car. My car is an Arntz (later known as a Butler).
The toe angle is usually built into the wishbones at 1/8 inch and should not need to be adjusted (unless you reverse them).
