Help! Accidentally removed power steering pressure valve

Not to steel the thread, But I might be having a similar issue like you did but maybe you can tell me if yours was doing the same... On my 74 dodge dart sport the steering is sensitive! Like It doesn't take much to turn the wheel when driving. By adding shims would this help fix how sensitive it is? Its pretty smooth other than that but its almost snaky when driving. (Upper & Lower ball joints replaces, Bushings, idler, pitman, and tie rods have been replaced)
