Okay I give up. How do you guys do this after you change manifolds? I have spent countless hours searching everywhere for anyone that sells exhaust plugs and NO ONE delivers on this. 4WD Hardware sells some half-sized crap that has the right threading but useless. Every industrial place in town has no idea what this is because it's a hydraulic fitting using fine metric thread while the OD measures 7/8" and everyone's catalog only goes up to 3/4" before they point me off to a wild goose chase that x company might have it. How am I supposed to get around this issue? I don't have a welder and fabrication is out of the question.

I picked some pipe plugs up at an old-time auto parts place. Not one of the big chains, but a place that has the counter built on a set of drawers full of hardware. I went in with a bolt and we found a very close thread. Just install them with some exhaust system sealer and they'll hold.
They used to be available at Team Wagoneer's website, and many other places. Most of the aftermarket manifolds needed plugs because they're universal and I believe AMC used them to cap factory fresh ones until they ran out of the old casting.

GRAH! O_o

It finally dawned on me less than a few hours since I posted this that 18m is a VERY COMMON thread but any bolt bigger than 3/4" is the major outlier that makes finding these next to impossible. Add to that my issue of figuring out how to search for specific bolts(for future reference the tag is 7/8"-18m) and this issue is just a huge mess. My mind is focused on the wrong stuff. I'm in the wrong headspace. My friend's Hornet uses this size and I have no idea why. I'm guessing his rebuilt 232 isn't from a Hornet but some Wagoneer that has these HUGE oil pan plugs that have been immediately put out of circulation ever since the last J-anything. The support still exists but it's barely there and way overpriced. Dorman part# is 090-011 and it's a real chore to find whether you're at O'Reilly's, NAPA, Central, Fastenal, Airgas, hydraulic shops or tractor supply places.
I was lucky enough to get mine from a NAPA in the next town for a few bucks. Most shops like Baxter want $$. Now I can finally reuse my intake manifold. Yay. :)
