67-68 use the Same Support/Hanger where 69 and 70 are different between the 2 years. The extra Width of the 68 Pedal doesn't make a difference for the Support. Power Brake Hanger only has one pressed-In nut at the Fire Wall Flange, Top LH. Manual Trans Hangers will have Beefier Metal Bushings on the Side to support the Clutch Pedal. Auto Trans Hangers will not.
