Interesting to me as I bought a 2005 Plus4 from Richard Thorne a year ago and he replaced the side screen window pillars prior to sale. There were no rubber/neoprene seals and the side screens rattled like mad on the 400 mile journey home. Since then I have adjusted the angles of the side screen brackets and used some door seal rubber to reduce the metal to metal rattles. I had no idea there was a factory remedy. Now there is no rattle, no wind noise and no water ingress.
