There is a metal bushing RD sells for the right side of the rack. On the left side the bushing is nylon, or like material. RD does not sell the left side part. You may also have to source the rack, pinion gear, and pinion bushing and bearing. The rubber bellows on the ends can be found at Rock Auto or parts stores.
Generally, the rack, pinion, pinion bearing, left bushing, are all in good shape and most likely don’t need replacement.
