OK so like it was pointed out earlier, I got the wrong WG for my manifold. It appears mine is flanged for a 50mm HKS wastegate from what I've been told.
My question now is, from what I've read the HKS 50mm gate is supposed to have a firing ting that is built into the flange. But my manifold flange does not have that. So WTF? Stupid Chinese maybe? I'm about ready to say screw that flange and cut it off and have someone weld on a flange for a Tial.
Here's a picture showing the firing ring built into the flange that I thought this is stupposed to have:
