With the front suspension assembled, the spindle gets dropped 3 inches (half of the total travel) from its fully compressed position. A digital angle finder was then mounted to the brake rotor so camber and caster settings could be made. On power-steering A-bodies like this Buick, Rod likes 3 to 5 degrees of positive caster,1/2 to 1 degree of negative camber, and 1/16 to 1/8 inch of toe-in. On manual-steer A-bodies, Rod sets caster at 0 degrees to decrease low-speed steering effort. All these settings must be done by a competent alignment shop on modern equipment. If you're lacking, it is OK to temporarily set it all to zero-using the digital angle finder and with the suspension dropped 3 inches-then drive the car to a good alignment shop ASAP for adjustment. Resist temptation to drive anywhere else; misalignment can wreck the front rubber in a jiffy.
