I wouldnt be pressing the cam bushings in or out of the CA, swapping the spindles, just the ball joint mount to the spindle (upper and lower), the balljoint would mount the same way to the spindle, with either CA. I was told its the force exorted on the Upper is higher then the aluminum control arm is
