Hi mate! Thanks for this awesome tip! VW Essendon Melbourne got me the parts in - the parts guy even mentioned he had never seen these "7H6" parts before - $236 all u, and future replacement blades will be $61 - that's actually cheaper than I can get the aftermarket "TRICO" aero blades that fit on the old arm mounts.

I've attached the receipt in case that helps future aspiring aero upgraderers
