I have a Mazda power rack similar to what’s in Cleo Shelby’s car… I use an electric power steering pump to power it. I have about 5k miles on the setup and it works very well. I’ve also done a ton of other mods to the front end including QA1 Mustang II coilovers, dropped spindles, crossmember brace to frame and ackerman correction. You can see some picks of the steering here…
