Hi John,
Honestly, the front flexi lines brackets being so close to the wishbone brackets, I just made the wishbone cuts in the GRP panel a bit larger. Finally, I think there is no need for a grommet here.
The hole enlargement doesn't need to be big, because the brake flexi hose movement is almost nothing that close to the bracket.
