I don't like scratching things up and forcing thing out and into place on a pedal hanger I always remove the steering wheel and column tube at a minimum to get to things easily. You can leave the instrument cluster in place as long as you can easily get to everything from underneath. If not, take it out by laying a towel on the painted dash so you don't scrape it up taking the wires off. Yes! Take the wires off and put it in the back seat or somewhere safe then you don't scratch something up pushing it out of the way while you are focusing on something else.
