This is a 2 bushing kit to repair 1 rear control arm.  Don't matter which one left or right side rear.  The arms are currently discontinued.  No fear! This fixes the loose end of the rear of your car.  You probably already replaced every thing causing looseness in the front end suspension.  Took me a long time, many shipments, to find these replacements. Used control arms, mostly are still going to need these.  Its a bit of work to drop the frame to access these.  Proper repair should have the control arms removed and pressed in and someone who has done bushings before.  Its approximately 5 hours to do both sides if your not a rooky.
