1974-1978 C3 Seat Back Hinge Pivot Bolt Bushing Kit 4 Pieces 339166 - OEM Number(s) (339166)
Restore smooth, correct seat back movement by replacing worn hinge pivot bushings and bolts that cause binding, looseness, and uneven seat operation.
This Corvette seat back hinge bushing kit services the pivot point where the seat back “irons” attach, allowing the seat back to pivot freely and stay properly aligned. When the original bushings wear out, the seat can feel sloppy, squeak, or bind during movement.
Replace the tired hardware with this correct-style 4-piece kit to bring back clean pivot action and factory-like function during your interior refresh or seat service.
