62 lancer pedal assy rebuild

I am swapping over from auto to manual . I started taking apart pedal assy. One of the plastic bushings is broke, does anyone know where to get these? Also the piece that goes thru the main frame that the brake pedal rides on, I tried tapping it out but it does not move much. Does it go thru a bushing? The pedal swings ok , maybe a little stiff but solid. Is it worth driving out or leave well enough alone?

thanks
