Crazy alignment problems

The rear track has nothing to do with setting the toe in or even aligning that car. All dusters had a narrower rear track than the front end. All you need is a couple of measurements on the front wheels one behind and one in front subtract one from the other and that will tell you what your toe in or toe out is. You lift the front end on one side and you crank the tie rod to bring that wheel in or out as needed.
As much thread as you had on those tie rod ends on that one side that is the one I would crank on first so you can bring those Wheels closer together on the front.
