Headrest Installation parts 68-70

These are for bucket seats. Removed from a 69 Barracuda, they should also fit for at least 68-70 seats (others too?). Chrome needs to be redone, but fine for a driver. Two of the plastic rings have hairline cracks (see pic), but all other parts are solid. Since the headrests aren't made to move once installed, the crack won't make a difference. $20 + ship.
