Dodgy conversion? You didn't even see it. It was nice work, he even lined up the new linkage in the same plane as the original linkage. DAT383 did a rack conversion, as did someone using Escort struts on a B110 circuit car. I haven't heard much about how those turned out.

If my choice is 35-year old worn out gearbox or an "some-say-it-can't-be-done" conversion, I'll give it the benefit of the doubt. Just because some race car builders have found a great solution doesn't mean it is the only way, or that it's not good for a street car.

They might also tell you that Nissan's original B110 steering gearbox solution isn't great for a circuit car. But it works well enough for most of us.
