The only thing you can adjust at most shops is the toe without changing parts.
The only parts they can change is caster with shims.
Any issues with camber (other than replacing worn kinpins/spindles) is a axle bend. And like otto said some rare shops have one guy that can do that.
Although you can sometimes find those guys at the big truck repair places as many big freight trucks still have straight axles. And a few of them know how to handle bending small truck ones as well.
its best to call the local restoration shops they usually know which alignment shops work on 50s vehicles
