Dang, my cowls on order and didn't know there were clearance issues.
How are the e92/e90 winshield nozzles mounted? Might be possible to retrofit the washers to avoid cutting into the plastic? I think the E90 washes are fixed near the black plastic trim below the winshield

I cannot find a picture on the internet showing where they are mounted, all I know is they don't sit on top of the hood like the e82 ones.
EDIT:
Attached picture of e90 plastic trim with integrated washers. What are the chances of that trim fitting an e82? I am guessing the shape is going to be off
