Leaking power steering fluid

I have a question, my 72 Duster is leaking steering fluid quite bad, it's leaking from the steering box I'm assuming? Im not sure the correct name of the part that it is leaking from, but the steering column runs into the part of said leak. The power steering pump hoses run into this part as well, is this the steering gear box? If so, what would be the best way to stop the leak, replace a seal? Any help would be greatly appreciated!

Thanks guys
