The 1969 Pontiacs received a major restyling with somewhat more squared off sheetmetal (though not as much as similar cars from other GM divisions) and rooflines, the coke bottle rear flanks were gone. However, the basic 1965 chassis, inner-body structure and four-door pillared sedan roofline were retained although vent windows were dropped on all models and Safari wagons got a new two-way tailgate that could be opened to the side like a door or downward like a tailgate - similar in design to that introduced by Ford Motor Company on Ford/Mercury wagons in 1966. Catalinas also got a one-inch wheelbase increase to 122. Headrests became standard on all '69 Pontiacs built after January 1. All 1969 GM cars (except the Corvair) got a new locking steering column that would become a Federal requirement starting with the 1970 models.
