For a regular O2 sensor of for a Cruiser one?
For a regular one, any exhaust shop should be able to get you one. I got the last one I needed at CarQuest.
For a Cruiser one, you might have a tough time.

Need a cruiser one...the flanged/bolt on style
They are part of the pipe that they are attached to.

And when some pos previous owner welds a leaking 02 sensor to that attached bung, what do you do other than buying a new downpipe/cat assembly when that O2 sensor goes out?
Walk, I suppose.

So the cruiser style bung can't be had?
it can't....not an independent piece on the exhaust system...unless you find someone who has replaced their exhaust and is willing to cut that part out for you...
check the thread/pitch of the stock O2, I know that for my GM O2 I used a spark plug fouler for $2 rather than a $9 bung...and it was avail at Autozone.
for that amount of work, why not weld shut/redrill/retap the stock opening?

Woody, on my 80 nothing is threaded except for the nut and studs that clamp the O2 sensor to the exhaust.
Yup. The 80 uses a flat plate with two studs sticking out. The nuts often rust clean off. You can generally clean up the studs with a die and then put new nuts on, but I've seen welded on ones before.
Can you cut the welds, or are the studs broken off too?

Studs are there, but appear to have been welded. I reckon I'll just see what the exhaust shop can do, hopefully they know something our collective minds don't.
Everyone's fav person to fight with (Sumotoy) posted a thread in regards to something very similar. I think it was a few months back but he swapped out the OEM O2 sensors for heated Bosche units and provided wiring info as well.
Edit won't work for some reason. Try this:

The Bosch sensors might not work due to a higher resistance of the heating element (probability of a sensor related CEL code). You can go for the NGK sensor as it is equipped with the right heating element and this should work better than the bosch.

I had a similar problem with my cruiser when I bought it. The studs were pretty heavily rusted.
On one set (rear I think) the exhaust guy welded a piece of scrap metal to the old studs, then removed them with brute force. he then cleaned the holes and threaded in a new stud. He said it was really not that difficult and it took around 30 minutes. It was really inexpensive for him to do this.
If that wouldn't work, plan B for him was going to be grind the stud down flat and just clean up the whole flat bung plate. At this point you could do one of two things:
1) have him weld on a aftermarket bung plate that has a threaded center like a spark plug- this is what the aftermarket O2 sensors will thread into. I now have one OEM 02 sensor in the rear one, and one aftermarket replacement NGK in the front that I spliced into the old harness.
or
2) drill into the flat plate and replace the studs with bolts instead ( much more time consuming probably)
Or you could just feed the shamans dogs!
Hope this helps.

What about finding nut replacements
I replacen my sensors and was able to reuse all but one of the copper or brass nuts. I just found another stainless flange nut to replace the bad one but worry about what effect the extreem heat will have. It might be even harder to get off next time. Can the nuts be ordered as a set. It seems like they would come with the new OEM sensors but no such luck...
