The article is in Car Craft and yes, it is very pricey. I was interested in what they did until I reviewed the cost. Now going to stick with what came with my '69 Dart when I bought it and just lower the pressure for a better steering feel.
One of the other benefits they were talking about in the article was about more room, assuming for headers, because of the smaller steering box. But then the car owner changed from headers back to iron manifolds so they never showed pics of the smaller steering box with headers.
