Flange that accepts both t3 and t4 bolt patterns
 

Where can I source one of these? I can't find them on ebay. I know ss auto-balls has them on their sr20 manifolds (and probably others) but I don't see them for sale by themselves.
I'm not looking for the adapter units that sell for 50-60 bucks, just a flange with holes for both t3 and t4 footprint turbos.
