I know these are available new from reputable stockists, and I might have to resort to that, but just thought I'd ask if anyone has any original ones? I think there is some kind of isolating mount / gasket that the new ones don't have. I have one totally missing on my bus and the others don't work, so before I embark on fixing them I may as well put one in! all the same I think but this is for a 76 cheers
