Here is a close up of the screen. LOTS of things you HAVE to pay attention to. When you change one thing, other things change! It is like riding on a merry go round. One of the particularly maddening things is tightening up the rod ends when you have everything "perfect." Just tightening up the rod ends changes the angles!!! So, you have to keep trying until it is PERFECT! When these cars are perfectly aligned...magic happens.
