I included the link more for the benefit of "others", Gav. But (as I say), the question you pose is a nice one. Can you not get away with simply following what the Service Manual says (I don't have it, so I can't really comment further)? Are you not happy with that? But as you've just said ("not sure"), you're obviously still mulling it over (and hoping, perhaps, for input from others). So let's hope we hear from those
others with this bit of kit soon!
