Not attached to the dash at all. Funnily didn't affect how it worked, even when pushing the cartridge in I couldn't tell. It was just an annoying vibration noise which I tracked down to that area and when I finally got round to taking out the glove box etc I could tell. Had a look at the google search and can see that those brackets are absent! Shame, Steve, that I took so long to get round to looking into this!
