rule of thumb here on front end setting...the adjustment cams (x2 per each side, located on the upper a-frame where they attach to framework) can be centered in the downward facing position prior to adjustment specs being applied. This will put the caster/camber pretty close to factory specs! I have done this several times and never had an issue. Good Luck, and find a reputable shop/front end man! Also, the newer machines for alignment may require 4 wheel setup, if this is the case, then the required rear wheel initial setting will need to be addressed with the computer guided components. To do this, we had to raise the rear framework from beneath (70 Dart) remove beauty rings, then attach the alignment tool to the wheel. Once the computer got the info it needed, we returned the body to resting height and proceeded with the alignment on the fronts...
