How can I tell if I have a manual steering column or power?

If we look very close at the steering shaft we can find a pretty weld bead all the way around the final member. So they're all the same length until this member is welded on. Weld at a inch or so from box coupling is power steering shaft. Lay your hand between weld and box coupling with space to spare, its a manual shaft.
