standard mk1 Scirocco lamps and grille, modifed the brackets and grille to fit the mk2. BMW lamps are same size as the mk1 Scirocco lamps so are a direct fit into the brackets with some jiggery pokery at the wiring end.
I followed the technote on the Vintage Watercooled website, but its not quite as straightforward as the author makes out, lots of measuring and cutting to get it right, for both the brackets and the grille, and various ways you can go with the electrics, but worth it i think.
