Some alignment help needed please.

When I took my Barracuda to my tire store for its alignment, I took the chart posted for the typ. street performance driving. Just out of curiousity, we went through the electronic menu and found that the oldest rear wheel drive mopar in the system (if I remember correctly, it was a 1985 Dodge Monaco) had the exact measurements on the chart and made it real easy to set the Barracuda to those specs. My car, with new BFG radial T/As drives beautifully.
