best to change both side at once = 4 bushings on strut rod.

I change one side only on the 68 Dart and got a 1/2" differance on side to side on the front end rack.

side I changed pulled the LCA forward 1/2" more than the pass side. changed pass side and both got pulled forward and got a spot on alinment.

strut rod bushings take a beating daily driving.
