Mine finally arrived at Chateaux Wales today after being held for ransom by the customs guys. Held them up to the tank. Left side perfect (and I mean PERFECT) fit, right side tight at the front a couple of mill max loose at the back. Will add plenty of RTV silicon sealant on the rear of that one.
Out tonight to meet a mate who has a load of clamps, which I can borrow for the price of a pint of London Pride, which seems a very fair trade. Won't fit them under the influence though
So guards arrived, meeting a mate, borrowing clamps and having a pint with a mate - not a bad day in my book.
Agree with all the comments on "oh yes, they are plenty strong enough".
