What is missing from this wastegate?
So I put my FD up on jeckstands to make a new exhaust and recirc the WG dump, and found what appears to be hardware missing from my wastegate. I can't tell what brand it is, and I don't know what is missing (at least some cap screws, maybe also a spring? Or a stud and a couple of lucknuts?).
Here is the WG (the dump tube had another 3" on it, I had just cut it to put a nice mandrel bent piece of 2" on it to join back into my DP):
Notice the two threaded holes?

EDIT: I am also thinking this one should have the boost controller input to the diaphram only, since there seems to be only one port on it. I know some get both manifold/controller.

Looks like a CX racing wastegate or some offbrand, 50mm maybe?
The center threaded area for preload adjustment is probably M6x1.0, though on a lot of the chinese wastegates they dont put a plate above the spring to give the bolt something to push down on. You could take it apart and inspect, if it's lacking the plate a properly sized freeze plug will work.
The other threaded bit is for using an electric boost controller with a 3-way valve. It should be 1/8 NPT
