gen 2 exhaust parts

Took off my Catalytic converters today to repair a small hole but went i went to put them back on i cross threaded 1 bolt and snapped another.
I've been looking for hours but cannot find the bolt the goes from Headers to Cats.
I looks like it threads in from the headers but no diagram i found online shows a part number or lists it at all.
I need the Studs, the nuts and i guess the donut gasket if anyone has it.
Any help would be appreciated.

 

It’s m10x1.25 threads. If it’s a bolt is .35 long. Stud is likely same length.

No better parts than Toyota tho. So if you can find that.

 

these are the factory nuts

 

the studs should be on the diagram with the exhaust manifolds

 

Cant find the Studs anywhere and toyota couldnt either when i called. Thank you for the factory nuts

 

Studs are 90126-10033 or 90126-A0011 either will work.
