The dials lift off as a complete section with the binnacle surround.
Lift it up and at the back of the binnacle near the front window you will see 2 brackets made of thin metal.
I put blue tack around them and then glued some foam type stuff to the sides of the binnacle attaching it to the dashboard.
Not a murmer now.
Off course you could shell out on a new binnacle surroundand take all your dials to pieces and swear a lot broker??
