'77 FJ 45 - 2f Exhaust part?

Apr 12, 2018
Hi everyone - finally addressing some things on my truck and just can't seem to find this part anywhere - or what it does?

It looks like this part has rusted and deformed a bit - leading to nasty exhaust fumes.

Does anyone know what this part is if it is necessary? Can I just fab something to plug this up?? This photo is looking up at the underside of the exhaust manifold - left side of the photo to the rear of the truck....

Any insight would be great - seems like a pretty easy part to find but can't seem to locate the right manifold or any other info on it!
