3.4L Exhaust Leak Help

After cleaning out my throttle body and IAC valve on my 99 3.4l, I found an exhaust leak. Its not where the manifold meets the engine its where the driver's side exhaust meets the exhaust tube that crosses behind the engine to meet up with the passenger side.

I am having trouble locating the correct gasket that goes with that flange, its not in the repair manual and the only things I can find online are a complete gasket set for the 3.4 or just the manifold gaskets. Should I try the dealer, or is there somewhere online that does have them?

Also, since I will be taking apart part of my exhaust and replacing one gasket should I just take apart the rest to do all new gaskets?

You can get that metal gasket from the dealer. You will have to replace the driver side manifold gasket if you headers off. I will warn you its tight in here. If you have Alot of rust on the joint where they meet good luck in getting them two to come apart. It welds together.

Only other thing to try is take it to a muffler shop have them fill in the hole by welding it shut.
