In order to allow the upper control arm to have full range of movement I had to notch out some areas where the arm was making contact before reaching the bumper stop bracket, now the arm can move all the way down and make contact with the stop. I’m very pleased on how the arms fit and function. Should work great for the dart. I want to make sure I get all the necessary things done to the car before taking it to the track and race. We shall see!
