Hi all, I want to dewiper my rear, does anyone know what size grommet I will need?

Really cba to dismatle it measure it and then re-assemble it to go to halfrauds then re-dismatle it.

Just remove the wiper, measure the hole and stick a bit of gaffer tape over it until you get the grommet.

could do I suppose lol, I feel a bit lazy atm

Use a bung from an old Citroen AX rear window.
