I was at work to day working on a 2007 Jeep Wrangler X 3.8L V6....and I was under the vehicle & I looked over and noticed the steering gear box. I thought hey thats clean & compact and would mount easily to square tubing. Its power steering & you may be able to get it in manual also. So here is a picture of the gear box its up side down in the picture.

I've got a very similar gearbox I didn't use on my Austin, but purchased for the project because a friend used one on his Anglia gasser. Mine is from an old Courier PU truck, and is a manual steering box. Very similar to that design too.
It was in the way for my setup, as the fenderwell headers and engine location dictated me making my small car a leading axle steer, so couldn't use the Courier/Mazda box. But they are very cheap at the U Pull It around here. I gave $35 for mine, but ended up using a Corvair van box and shaft. Cost me $100 for the Corvair item.

that box is the one everyone uses for 1955 1956 1957 Chevy power steering conversions. It's the "new" "500" series GM box found in pickups and regular cars, but the pitman shaft is shorter in the cars. It's probably the best power steering box around now.

This is the Mazda/Courier PU box when I was trying to mock it up on the Austin. Pretty compact, and the nice part is it's tall, so it spans the frame allowing the arm to be below and the input above the frame.

Hey 1946 austin do you still have the courier box? I know this post is old but thought I would check.

Sorry. Actually I do, but it turns out it will be perfect for my Falcon gasser project. I just pulled the pitman arm off it last night, and after I grind the index notch out I'll reverse the arm 180 degrees, and put it on the Falcon gasser.
You might check your local wrecking yard for a mid 80's Mazda or Courier pickup steering box.
