battery panel hole sizes ?

[Itsblue]

Can any one advise me of the sizes of the two holes in the battery panel under the drivers seat ? mine have rotted to nothing so have repaired the panel but could do with the correct sizes to refit the grommets ,

Thanks in advance

Make the holes to suit the grommets is the obvious answer - not difficult to find the diameter of a circle (The 'groove' of the grommet).
