Hey, I have a 2009 2.5si roadster, recently purchased and the exhaust clamp on the underside of the car is really corroded. I need to change the exhaust clamps/hangers but cannot find them anywhere as they don't seem like a usual hanger. They are bolted through a weird twisted connecting plate (part number 1820 7586704) but I cannot find the clamps that bolt to this anywhere at all. They are on the exhaust located pretty much just behind the driver seat if you like under the car, can anyone help at all??????????
