Sorry for the delay. Yes, I re-used all bolts including the spring loaded collector bolt. They were all in excellent condition, even after $35K miles.

One thing I didn't mention in my original post, I don't know if this is just my car but there is a threaded tab on the side of the header (new and old) that wasn't connected to anything and doesn't appear that it could be. Is this supposed to connect to the "support bracket" you are talking about? If so, my car didn't come with a support bracket.

As I think mentioned before I'm a little disappointed that I could not reuse the spring loaded bolts as the thread pitch is wrong. I'm glad to hear the DC's were a match. I also bought longer bolts for the header that hold it to the engine block, I just didn't like how little thread there was left due to the thicker flange and thicker gasket.

Yeah, the support bracket is basically in the shape of a triangle, two bolts to the engine block and one to the threaded tab. I wonder why yours didn't have one? Sedan vs hatchback?

Oh, I now have a new air/fuel sensor, just haven't installed it yet. Probably tomorrow, then I can start driving my Yaris back to work and get a feel for the new header.
