Hello all, like the title states I need to find out these two flange types and 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.

Here's a picture of the stock manifold.

these are the gaskets of the two flanges I need. Inlet and Outlet
