Manual steering box
Copy that. Steering coupler could need to be rebuilt as well.
I had a 20:1 PST manual box on one of my cars before I sold it and was happy with it. Requires a little more muscle when parking and it's a little more difficult to back into spaces but I preferred it when out on the road. Not having the dead spot in the center and turning the wheel 50 revolutions to do a u turn was nice.
