Anyone here swap an aftermarket power steering box for the OE box?

Typically, the later recirc ball type steering in the later 69 and 70s give an easy steering experience compared to the earlier model roadsters. I was amazed at the ease of effort required when steering one when I drove a car with it. Night and day difference and much easier to implement than a power steering change.
I have seen powered steering on a car or two at the Solvang show years ago, so yes, it can be done, but the cars I saw it on, were heavily modified all around and I would say they had the money to invest in the change based on the total car's worth.

Thanks Greg, I have heard that about the recirc ball box. I wish I could try a later 69 or 70 but they’re so rare here in the northeast making that very unlikely.
I’m working on a SN95 mustang 5.0 swap so the front will be 100-130lbs heavier and I’d like to go a bit wider than stock on front tires. I have an 04-09 Prius electric pwr steering system coming and will see about mocking that up soon on my early ‘69.

There is/was a company working on a rack and pinion steering swap but I don't know if it is still in their plans or not to complete the project.

I had not seen anything on a rack and pinion conv kit. When I needed a roller I tried to get a late 69 or 70 but just wasn’t able to. The cost for a late 69 or 70 box, pitman and idler is high unless you can catch a break. The Prius EPS will work ‘IF’ there is room for it. With the collapsible column, under the dash is likely out. It appears the only possible location (in my case) is pretty much right off the box. I’ll have the Prius EPS tomorrow so I’ll start looking at the possibilities soon.

Someone has done it with pictures, not sure how to search for it.

Looks like Vinechoy accomplished it

And you loose the death spear column in the swt.

Got the Prius EPS yesterday. Bench tested it and it is amazing. Default w/o speed sensor connection will be 43mph. I looks like it will feel well under the dash. The big thing is the shaft connections down to the steering box and especially to the steering wheel such that the original ignition, etc and wheel can be maintained. Will have more on this however most mockup will be on my roller outside and it's starting to get very cold here.

Even back in the 70's (like forever ago) I thought a rack and pinion set up would be cool! Just think of the weight savings you could achieve! The steering box is heavy as is the idler arm box and all the linkages. Surprised someone hasn't commented about having tried it. Racers? Autocrossers? Any thoughts out there?

These were the guys who were making a new steering box for the Roadster. They once showed it on their site as an up and coming item and I even emailed them about it
