Here is another view
This is sort of what you see looking up from underneath.
D is drivers side
P is passanger side
The bottom of the photo is forward
The green dot is the adjusting bolt
The blue dot is this particular bracket has been bent (it should be straight) the switch should be centered on the brake pedal arm
The adjusting bolt head is accessed from the passanger side.
There is a tang that goes through a slot in the pedal support bracket. Just up from the blue dot.
