This 1958 Chevy Impala Rear Lower Trailing Torque Control Arm OEM is an original GM part that has been media blasted and painted. The LEFT and RIGHT trailing arm are interchangeable. The control arms come with USED bushings but for an additional cost we can press on new bushings.
NOTE: The major difference between 1959-1964 lower control arms and the 1958 is that the latter has two small bushings (1 3/16") compared to the 1959-1964 that has one small (1 3/8") and one large bushing (1 5/8").
Width of bearing shaft from inside the control arm: 1 3/16"
