Early 911 Steering wheel

Can someone help me? I have a 1966 911 and I have the original wheel, but have none of the horn parts for the wheel. Does anyone know where to get such parts, or diagrams/ exploded view of how the wheel and all its pieces go on the steering column. Thanks

I have an original early '67 911 wheel and horn. Wood wheel, black stripe, winged horn rather than pushbutton as my old 912 had.
