I think it is not absolutely necessary to disassmble the whole mainboard. Do the steps up to 27, then disconnect the 4 antenna plugs from airport card, lift off only the right speaker, remove the two screws from airport card and with caution you can now lift off and change the card. I do this so and it’s faster and not so difficult like disassamble the whole imac.
