I have switched from automatic to 4 SPD. Manual brakes to PDB. I have a 9" booster with adjustable rod. There are 2 holes to attach the clevis to the pedal, should I use the top or the bottom. I believe it is the one that would allow the pedal to be closer to the floor pan. It looks like the original location of the brake light switch is too far from the pedal to work. Do I need a different part or is there room for adjustment.
