The specifications for alignment are in the Service Manual, page 3-16. Caster is set by shims between the axle and springs and shouldn't need adjusting. Camber and king pin inclination are only adjustable by bending the axle, which shouldn't be necessary. About the only thing that's easily adjustable is toe-in, and you could do that with a ruler in your driveway. But an alignment shop can check everything, even if they don't have the specs in their computer or alignment machine.
