How to "rough in" front end alignment after rebuild?

I don't do toe that way if that is what your referring to. Crackedback mentions this. He just lays a board outside of each tire on top of something to block it up so you are measuring about spindle height, and sticks out the front/ rear of the tire so you can lay a tape across for toe measurement.
Like a 28" 2x4, on a cinder block?
