Power steering conversion for old push/pull box

[Detour]

Well I spent a lot of time pulling a steering pump, box and shaft out of a square body last week hoping to convert my truck last week. Got it home only to realize that my steering bod is a different style. Every truck saw a the junk yard had the pitman arm on the bottom of the box for a left/right movement. I have a Saginaw with the arm moving front to back.
Do I have any options?
Thanks

Oh man, I almost commented when you posted the thread about Junkyard PS Swap a while back, that you have bigger problems than what you were trying to figure out then, but I thought you might have already figured that out.

I'm not sure there is an easy answer to doing this with a closed knuckle front end.

You would definitely need the later power steering gear, because there is no power option for the style you have. I have 67 K20 also. You will either have to dimple the 67 frame or get one of the adapter to allow it to bolt to the frame(or spacers). You'll need a different rag joint too.

Then you have to figure out if you can get a steering arm to replace the one you have on the top of your knuckle right now. I'm not sure the later 'open knuckle' steering arms will fir the closed knuckle.

If you are going all the way, you might consider a "crossover" steering conversion.

You might call off road design and tell them what you are doing and see what the recommend.

You could also call the guys at Torque King and see what they recommend. They have lots of parts for the old closed knuckle stuff and are very knowledgeable.

Have you checked out electric power steering.
Not cheap, but I’ve seen threads on other forums about junkyard cheaper (200-300 buck) set ups that can be used.

Yeah, I have looked at my steering box enough times, I don't know why it didn't register that I had different geometry. Not the end of the world. I'll clean up what I have and toss it on the shelf in case I do an axle swap in the future.

Thanks Geezer, I'll have to research electric out of curiosity.

PS isn't a must, I'm just doing enough other stuff that it was tempting.

There are some good threads in the 60-66 area about K20 power steering.

Here's one:

Or here's a link to a google search of this board, you will just want to look at ones dealing with 68 and earlier:

Seems to be find used later model open knuckle front diff and power steering gear box, draglink combo is a common solution.

I also had this saved:https://tuckersparts.com/products/67...ubber-hose-set

I would call Tuckers and ask them will their setup work with your closed knuckle front end and how. Seems like it has the same parts you already got.

I keep hoping someone more knowledgeable will come by and offer you some solutions too. I was never too serious about converting mine to power but looked into it briefly. What really kills me is the turning radius. I can barely get the thing in my driveway(without driving over the curb and/or in the grass), if cars are on the street in front of my house.

I was looking at some more of the posts in that google search and came across this one:
