I have a Limited Edition GBA SP AGS-001 (dull screen) and I wanna replace the guts with that of a AGS-101 GBA (brighter screen)

now, I have no worries about doing this except 1, there are 5 screws that go around the display on the GBA SP. that have rubber screw covers.

whats the best way to remove these covers with out nicking the covers or the plastic housing as much as possible? I've tried a small flat screwdriver and a utility knife blade in the past and there's always been some damage.

I just like to keep the NES GBA SP looking as good as possible.

thanks!
