I have one from them on my '70 with crossover. It's probably 7 years old now and working well. I talked to them about what I wanted before ordering. They built it custom since I wanted to step up to the faster ratio. They set up the torsion bar inside for a nice response. I drove another one from Benchworks that worked well, but sold it years ago.Anyone ever use these guys? https://benchworksteering.com/
Did you go with the 3 turn or 4 turn box?I put a redhead on the wifes k5. Super smooth, And that's with crossover steering and 37" tires.
