You can get a set of the second design 9C1 rear lower control arms - 10289786, New Design 9C1 Lower Rear Control Arms - for less than the cost of the bushings. Current price list: $138.82 dealer cost: $79.13
Boy, that is double what I paid two years ago. Dal should be $87 or so + shipping. This kit comes with the bolts, nuts and washers to fasten the 9C1 rear bar. Still a deal over the PITA of changing bushings.
