Plastic crack or not, depends on how careful you are when you dismantle the trim. Even the screws holding your ac button can break off. I am not so worried about it though. That trim is replaceable.there is uncle in Puchong that knows how to repair the meter panel.
i have issue with my trip meter. dare not touch... worry some plastic will crack for this old car... lagi banyak problem
What you need to be more careful about is those connection strips at the back of the meter
