HomemadeTurbo - DIY Turbo Forum - What are these turbo flange styles called, and where can I find them?

Hello all, like the title states I need to find out these two flange types are called and/or possibly where I could buy a bare flange piece to build a custom manifold and downpipe using them. They are OEM Mazda styles. I'm going to be using a stock k04 Turbo off a CX-7 / Mazdaspeed3 and am having trouble finding what I need online. I'll attached pictures of what I'm looking for. I shouldn't need anything to specific just a basic Steel flange template anywhere from 3/8 to 1/2 inch should work. Any help would be greatly greatly appreciated, I'm on a deadline to get this turbo on my race car and get it running ASAP.
thanks in advance, Bill.

In this picture you can see the gaskets as an example of what im looking for. Maybe I can use the gaskets as a template and make my own, just don't know if it would be easier to Source them somewhere online. Maybe find a CX-7 in the junkyard and cut the manifold and exhaust downpipe to use that as a starter?
