It takes minutes to change over. You’ll need a hex key to remove the panel over the air bag. Disconnect the car battery first and go for a cup of tea to allow any current in the system to disappear or the air bag might go off!
Never had one go off yet but best be safe.
I have a spare real wood walnut dash and a spare later plastic walnut one.
To be honest, I’ve not tried to sell either as I’m a hoarder of spares “just in case”.
