How to Remove the Brake Pedal Assembly Bracket

[hodag]

I am trying to remove a (automatic) Brake Pedal Assemble bracket from a 1986-8 S10 Blazer. I have removed the Booster 4 nuts and the one bolt up front by the dash. I have also dropped the steering column down and out of the way. I also have pulled the clip that holds the booster's rod to the brake pedal. But the Assembly Bracket still feels solid in place, as there are more bolts or nuts holding it. I did not remove the nut and bolt that hold the brake pedal in place. What is this old duffer missing I need it for my 1949 Series 3100 Chevy pickup. Your help is appriecated.
