Are most o2 bungs the same size? The pipe I got with the cat and rear o2s is off a 98 dakota. Should it matter?

I went to the local auto parts place (a real auto parts place, not a Autozone, etc) and they carried O2 sensor plugs. Were about $1 apiece.

Beware any flush-fitting plug like the Allen head ones
that come with Innovate widebands; they will gall in
place and not come out. That's why I like the oil pan
plugs, nice beefy hex head to grief on a couple years
from now.

All the sensors I've seen are standard 18mm spark
plug thread. Meaning I guess that if you were a real
cheap bastard and saved up used lawnmower plugs,
you'd be in fat city.
