I just realized that I didn't really explain how I felt about the feel of this steering box.
I was really impressed. The car didn't feel like it wanted to wander like before. The center slop is gone. The steering effort is much easier. I was used to the high effort that the Firm Feel stage 3 and the longer steering arms delivered. The turns lock to lock are about 3 1/2.
I did expect the steering to feel a bit heavier but I was not disappointed with it. Since the car has a 5 speed, having the steering a little easier to operate is a good thing. I want to teach the wife how to drive a manual transmission so this will help.
No leaks, no noises. I still have the Saginaw pump. In fact, I am currently switching to a hydroboost brake system that uses power steering pressure to assist the brakes.....
