I am looking for a way to change the adapter type on the Audi A8 so it will accept standard wiper blades.

I was hoping for some sort of cheap plastic adapter which I could snap on so it would accept a stock blade, but am not afraid to swap out the whole arm if it means I can use standard wipers.

Any help appreciated, or links to applicable parts. I have seen a lot of Aero adapters/retrofits for the A4, but don't know if they fit the A8 (I assume not)
