Also, a place called Radiator Express says on their website regarding SVX radiators "this item has been discontinued. However, you can opt to use a Subaru Impreza radiator in it's place. It will require modification to the top hose, pin mount and oil cooler. We handle stock and all aluminum upgrades for the impreza. See part numbers like 221061, 222043, 217785, 221955". So maybe they can make the alterations for you.
