Stabilizing the lower arm and strut rod are so important in creating a tight suspension, but it takes the purchase of some pricey parts.
Could you give us some examples??
I have the PST urethane LCA bushings with all stock components in my 67 coronet. Have always had a clunk in reverse, predominantly the right side ( passenger side).
Are you saying I would need adjustable strut rods to eliminate this using Urethane bushings?
