I recently bought a Blitz Super Sound BOV from Ebay, used from a Japan. It came with this little adapting flange but it was pretty much useless. Where can I get one that fits the SS, not the new DD Blitz BOVs? Summit says they sell flanges for the SS in their magazine but they show pictures of the DD and call it the SS so I do not want to buy it if it is the wrong one. Thanks in adavance guys.
