Default O2 Bung Size?

My builder has finished my heads/cam/LT header install with one question I couldn't find while searching the forum:

What is the size/pitch of the O2 sensor bungs? I have 5 of them in my exhaust, 4 for the actual sensors and 1 for an air/fuel sensor when tuning. We simply need a plug for that hole while its not being tuned.

I called England Green (great guy!!) and he told me an 18mm bolt with a 1.5 pitch should fit. Can anyone else verify this for me?

Many thanks,

I can't verify the size right now but if you need to order one here is a good site.

Linky no worky.
I'll manually look through their site though. Thanks.

Think I found it:

Question: How do I know this will fit...or are all O2 bungs universal in size?

Thanks again,

This one's cheaper and I believe it will work just as good:

Good stuff. Rossi's link seems to support the dimensions Jason gave me.

18mm, 1.5 pitch.

Thanks again,
