Perhaps I wasn't clear. I am not looking for a new one for $200. I am looking for one sitting under someones bench gathering dust.
Same ebay person has several square ones too but lists them as being for a K14http://www.ebay.com/itm/VW-TURBO-EXHAUST-FLANGE-DOWNPIPE-AAZ-K14-DIESEL-MK3-GOLF-JETTA-PASSAT-3-/141063848337?pt=Motors_Car_Truck_Parts_Accessories&hash=item20d80f8191&vxp=mtr
If it came from an AAZ and has a four bolt square turbine outlet flange then it isn't a K03. It's either a K14 or a T2.
