Mount daytime running light in Corolla Verso, disassemble front apron

Hello people, here in the forum there is a post with photos, by a member has the daytime running light installed in the aperture of the fog lamp. I also want to try this good idea, however with LED 70mm diameter. I ordered these headlights and notice now that they do not hold so easily on the fairing of the fog light, but have to be installed in the front apron. MY QUESTION: how can one remove the front apron. I do not want the good part on good Unscrew luck, and then some plastic part breaks off! Then the daytime running light is fixed in the apron and the aperture is inserted again. When everything is finished, I can set a photo here.
