So I'm trying to clear my corner on my 2000 Z24. I've got the guidelines by Marco, and have gotten to where I'm removing the orange plastic covering. I've chipped some pieces out, but most of it is still there, and I can't figure out how the rest of the piece comes away from the lense. Do I have to give it a good smack. Any tips or suggestions would be very welcome. Thanks

Rinse with a little water and let dry before you reinstall it.
