I've attached 3 pictures of a Wheel alignment tool for Matco Wheels & Axles. It is simple to make and gives the user a perfect platform for wheel alignment. I hang a plumb-bob from the nose and prop extension and use a laser level to project a center line on the floor and Plumb-bobs. I then place a second laser level on the MAT tool and project a line on the floor. You can then easily take the measurements between the two laser lines. I use a U channel to raise the nose wheel about 2 inches so the laser will show all the way to the nose. Two bricks and a piece of plywood will work.
