I have a 68 ss rs bb car with the 5 leaf springs. I would like to install new bushings and when I removed the old ones it appears that they were both installed on the same side. When I measured each side, one side was 1/2" the other approx. 3/4" . The outer steel jacket measured 2 1/2". My question is should I install them on opposite or does it matter if they are on the same side. Thanks for any advise.
