This 1965-1966-1967-1968 Chevrolet rear upper trailing torque control arm is an original GM part. The arm can be used for both the left and right (or double setup as in the case of a wagon). The trainling arm mounts to the bracket on the rear cross member of the frame. The control arm comes with used bushings. For an additional cost new bushings can be pressed on.
