One sway bar, a bushing on each end and two on the frame. You have the entire set of bits for the car, both sides.
The older swaybar setups had four bushings on each control arm, and two large bushings on the frame. On the W124, there is a circular bushing on the control arms and two circular bushings on the frame.
Be careful not to twist off the bolts welded to the control arms.
