QUOTE Wilemans ,we have sold hundreds of these kits with no problems,
If you had asked me to bet my life's savings on what their reply would be, it would have been exactly that!

Do you still have the old curved washers, as they are often re-usable? But if the washers you have been supplied with are 'paper-thin' then they should be OK.
