I turned the Spirtster bottom mount post backward and remived the bucjet post. With a washer slid in as a spacer the Spirtster headlight mounting post fitted this 7 inch headlight shell. I used a rubber seal to sit a 7 inch LED sealed headlamp unit in the bezel and secured it with the W clios supplied. It all fitted into the bucket shell and looks exactly like the original XL1200CX headlight, just bigger. I am very pleased.
