Go to Longacre`s web site and then to the Tech section . They have a great "how to " article on Squaring a Race Car .... from theory to practice . They align/square the rear end to the front suspension , not the frame , which makes sense .
Now to go out to the garage and see how much I`m off after doing it the way I have for years !

P.S. They are talking about a circle track car , but the basics still apply .
