I noticed one of the nuts on my exhaust manifold is missing. Any one know the size?

The ones holding the heat shield on are 8mm 1.25. Not sure about the ones into the block

that is such a common size on the Fiat, buy a bag of 10 and keep them in a bin on the workbench.

Are the original nuts on the manifold brass? I recall the originals on my car are a brass or bronze but could be mistaken.

I know others have used stainless steel which may be preferred.

Not sure but the stainless steel ones were out of stock, so I just bought the regular steel ones.
