Many thanks, Drew. Truckernix, I guess I'll follow the easiest way (Loctite). By searching "loctite", I found two posts from Carbking (page 2, 25 Feb. 2009 and page 3, 17 Jul.2008 and another from Cavebull (page 3, 17 Jul 2008), all three endorsing the use of the adhesive. Thank you for the valuable advice.

Fabio.
