According to our home page information....... 3814682 and 683 are correct for 1962. 1962 will have date codes, later models do not. Center dump style. Very late model 1962 could possible have rear dump manifolds, 3822924 and 925 but I would think them to be very rare. Most 62s had the center dump manifolds.
