Steering Box - What model is this? Should I upgrade to power?

I never have understood why anyone would want power steering on an A body, unless it came that way. Even then, unless it was an original performance version, I would change it to manual. THey just aren't heavy enough to need power steering. Maybe if you're a really light small woman....

I'm going to convert because it gives me the faster 16:1 steering ratio and I have the parts. So $0 investment beyond the sweat equity.

Don't have an issue with the effort to drive the car with manual steering, been that way for the 20+ years I have owned. But the hand-over-hand method of going around the round-abouts has me really wanting a faster ratio. Was going to do the PST 16:1 box, but could use the money elsewhere.

Wait, technically maybe I don't have all the parts. The coupler on the PS column is beat up and I need a pitman arm. Still far cheaper than the new box I was going to buy.
