I have the aftermarket upper and lower control arms. They are the "overseas brand". I would like to replace the bushings with rubber bushings but I can not find any or any info where to get them. The uppers has had the bushings removed and they have been ruined. The lowers are urethane but would like to install rubber bushings. I called the place where they were bought but was told they just sell the complete control arms, no parts available. Went to the local parts house, that was a waste of time.
