I ordered matte black side gills for my car. I know how to get them in and out of the car, my problem is once they are out the chrome piece is attached to a black plastic casing (this has a honeycomb look to it) and i cannot figure out how to get these two apart so I can replace the chrome with my new black ones and put them back in the car. Please help, and remember this is for the e90 side gills not the e92!
