I installed these in my 75 280. I also went with their lower control arm set. After I got the car aligned the tech stated the the rack was in good shape. I was wondering what he was saying as I always thought I needed a new steering rack. I was amazed of the responsiveness and tightness of the steering. Road feel through the steering wheel is noticeable, not obtrusive. Driving over bumps (city/highway) the steering wheel does not jerk though. With these two items I do not need a new rack. Before there was too much play n the steering wheel. Btw, I had previously installed the aluminum/delrin camber adjusters in the control arms. I would not recommend these. I had a knock in the rear that I could not figure out for years. I took the metal camber adjusters out and installed poly bushings. Result , no more knocks.
