68 Barracuda Manual Steering Box

Mine was like that too, like a dead spot in the center? Have someone yaw the steering wheel back and forth while you look at the gear box. The sector shaft on mine (20:1 PST) would move side to side considerably before it started to rotate. PST sent me a new box no questions asked, but I haven't been able to get time to swap it out to see if the problem went away yet.
That is exactly what I did to locate the issue with the slack and exactly where the issue was. A bunch of slack before the wheels start to rotate. PST is sending me a new box as well but the time it takes to install a second time around to see if it fixes the issue is a huge inconvenience. If this is indeed a manufacturer defect PST needs to address this issue if it is common. Hoping that a new box fixes it and if not, very unfortunate that this was a recommendation. Hoping to hear back from the marketing manager from PST on this thread.
