They are real devils to remove, almost impossible without breaking the tags. My Cup, (no high level light as it's in the rear spoiler), had a faded panel due to UV exposure, so I decided to give it a bit of a refurb. The speaker covers had faded too but these were easy to swap with replacements from a breakers. The rear panel was eased as gently as I could, but still lost one tab !!!! I then got a black magic marker and 'coloured it in ' to give it original colour. I managed to reseat panel best poss but still didn't fit flat. I had recently purchased an aluminiun tax disc holder which had remarkably sticky double-sided pads to stick to the screen. I had two spares of these and used one in place of the fourth tab. Works great as long as I don't plan to remove it again.
