[MIKEVYII]

Hi Guys im getting a mobile paint repairer to paint & repair the front bumper on the AU (brought it like that) & he also going to colour code My mirror covers, but i have to take them off for him. had a look today but there is no screw underneath like ea's. So how does one remove the side mirror covers on a AU/BA/BF?? thanks
