| These ball joints will fit either side of the Z car from 71-78. To install them on a 1970 you must change the steering knuckle to a 71-78, or order a different ball joint. See listing. These ball joints also fit the PL510's from late 1970 to 1973 that use the 14mm shaft. We can usually get these ball joints on a daily basis in case we happen to be out of stock.
