Ok time to find a rubber mount then! A longer bolt and a rubber insert will do the trick to take the weight of it when full. Rubber behind it between it and the support bar?
May I ask if you have any spares? My chances of getting to a wreckers inside a fortnight are very limited.Given I am off to Italy on the 26 of next month its possibly 10 weeks away!
On a happy note Catcams 4903109 on order to liven it up a little.
