Lower control arm sway bar tabs not the same height
After looking closer I remembered that way back in the day I had a new lower ball joint installed on the drivers side. At least 35 years or so. Before the days of Chinese crap, but still a local parts house replacement. I took these pics to show the difference in the two sides. The tape measure on the right side is touching the lower part of the eye of the arm and the drivers side is below it by about a 1/4 to 5/16 in. The drivers side lower ball joint puts the lower arm higher than the passenger side which still has the original factory lower ball joint on the car. This would explain the differences in the two sides being different as far as the sway bar mounting is concerned. Anything to worry about as far as having two different lower ball joints??
