Hi, I need some input about those plastic fasteners or clamps that are used to fix the windshield washer hose to the bonnet. My bonnet has 6mm holes for this purpose but the clamps I bought from W&N are too big (8mm) and I don't want to drill larger holes in my newly painted bonnet. I have seen clamps on later BMW models that might fit but I have no reference to part number or size.
