Thank you for posting my photo, Raphael!
To Stringer's BM:
Yes, the clips are vertically sprung, but the hard rubber pads are tensioned against the cowl, providing a sort of miniature triangulation.
Hot Radox baths and shots of Aberlour have both proved useful, but I have also visited a back quack who has worked wonders. The second visit was considerably less painful than the first, which I think is a good sign.
Incidentally, I am still thinking about how to blank off the Dzus orifice, the problem being that there is not much space on the other side, between the cowl and the Dzus receptacle.
