Stainless O2 Sensor Boss

[browny]

And I thought this would be easy.

I'm simply after a SS O2 sensor boss. So far everyone i've called has said they can't get them. One guy even went as far as saying using SS would make it difficult to remove the O2 sensor at a later date (?).

Does anyone know where I can get such a thing from?

You could try getting a stainless 18x1.5mm nut from a fasteners shop, other that that no idea sorry.

I tried. They didn't have anything that big in SS.

just get one made up , machine shop should be able to do it.
going to be one expensive boss tho , but it aint going to rust.
