Need help with bolt for obd port on header pipe

[Autonut]

Somehow and someway I lost the bolt that goes into port on header pipe? It look’s proprietary. Is it?
Something off the shelf at O’reilly’s? Has the look of a drain plug.

First start yesterday and some minor exhaust leaks. Snugged everything up and still can hear a leak? That’s when I found the culprit. Any help appreciated, size, locate etc. Thanks all.

Are you talking about the plug for the oxygen sensor bung? If so, I may have one.

Yep, I've got one leftover from my MkIV SBF headers. I can drop it in the mail if you want it. PM me.

Hey Greg,
Thanks for the quick response and for your generous offer. We found it….well actually the wifey found it down the driveway a bit. After me searching everywhere in the garage for 45 minutes, she find it in less than 2. Lol. Thank you again, I got lucky today, real lucky.

Sweet! Gotta love the easy solutions. Seems like that doesn't happen very often.
