The toe board on Sparky needs some repair and parts replacement,

1) The gas pedal rubber covering is shot and needs replaced or the whole pedal replaced. How is the pin holding the pedal onto the board removed? I tried punching it out without any joy. The pin holding the pedal has a small hole on one end, as if for a cotter key??

2) There is a small hole on the angled bracket holding the pedal onto the back of the pedal. Is there some other part, missing? If so what?

Any info help will be appreciated.
