For those that want spare or replacement windscreen wipers, they are standard Bosch aero blades. No fancy fittings just the regular type so should be able to buy online if you have the right length.
Must be part of the arm. Here’s a picture of a spare rear wiper blade. That was in stock for Ineos. As the front ones weren’t in stock I was told by the technician that Bosch aero blades are a direct replacement. I’m not with my vehicle at the moment but when I get to measure the length of the front blades I will order spare Bosch blades. If anyone has access to their Grenadier could they measure front blade length please.
