Please let us know how it goes. I was looking at your realoem links, but I couldn't figure out which parts numbers correspond to 65mm, and 70mm. I thought it was a bit bizarre as they seem to use the same part numbers in both cases. I'll go and measure the pipe when I get a moment, but I am not sure if that really matters too much anyway.
