The headliner does not need to be touched. All the steps are exactly as described in the original write-up.
I would just add that it makes sense to use threadlocker on the nuts securing the bracket to the wheel well. See attached pic, red stuff on the nuts. It ensures that the nuts will stay in place forever. It also protects them from rust. Otherwise vibration, temperature changes and humidity may cause them to loosen over time.
