You'll need a dremel with steel cutting blade & long nose pliers.

pic1 - make template of the chrome reflector.
pic2 - template of chrome reflector.

pic3 - use dremel & cut/remove the "4" tabs indicated by red arrows.

pic4 - 4 tabs removed, all you see is the lip around the reflector.

pic5 - center smaller yellow reflector over template.
- use marker, mark the "6" cut lines on the lip.
- black out the "2" notch areas to be removed later.
