The 1969 model did not have the vent windows, had a slight grille and taillight revision, moved the ignition key from the dashboard to the steering column (which locked the steering wheel when the key was removed, a Federal requirement installed one year ahead of schedule), and the gauge faces changed from steel blue to black. In addition, the rear quarter-panel mounted side marker lamps changed from a red lens shaped like the Pontiac “V” crest to one shaped like the broad GTO badge. Front outboard headrests were made standard equipment on all GTOs built after January 1, 1969.
