I moved the brake pedal over on my chevette; what I did was remove the snaprings that held the top of the pedal from moving side to side on the pivot shaft. Then i slid the pedal over to where I wanted it, drilled holes through the pivot shaft on both sides, and put in some cotterpins to keep it from moving side to side. Next I knocked out the 1/2" pin that the master cylinder rod clipped onto and replaced it with a 1/2" Grade 8 bolt so that it would reach to the master cylinder rod. I put the bolt through the rod first and then through the pedal so the rod would have a smooth surface to ride on. I put nuts on both sides of the pedal so the bolt wouldn't have any play and drilled a hole through the bolt shaft next to the master cylinder rod and put in a cotter pin to hold the rod in position when the pedal is being depressed. Finally I cut off the tab for the brake light switch and re welded it to the pedals new location.
