I had a Scirocco a while ago that I put a header on. It didn't have a boss for the O2 sensor so I blew a hole in the header with torches and welded a nut the correct size for the sensor over the hole. Then I just screwed the sensor into the hole.

Would this approach work for a 'tour instead of elecronic eliminator gizmos? Just curious . . .
