Do I have a Manual or Power steering column here ??

I just found a steering column for my '70 Challenger, but I can't remember how to tell just by looking at it, if it's for a Manual, or Power Steering set-up.
I know that the Manual Box needs a Longer steering column shaft, but without one here next to it, how can I tell ??

Thanks.....
