After several hours at the hardware store I have found something with the same thread as our air suction pipes. For those of you who don't know the A/S bung is the large one in the center of this picture here:

This is what I purchased for about $7.00 at The Home Depot:

It is a 3/4" brass union for copper pipe (NIBCO 733 BRASS UNION SIZE 3/4" QTY 1).
Take apart the union and discard the copper piece and the nut:

Next you will need a bosch style O2 sensor. These don't have to made by bosch, but they will look like this:

Next take the male part of the union that you saved and install it on the O2 sensor like this:

Making sure that the nut part of the sensor is in contact with the male part of the union, install into the bung:

You may need to pull back on the sensor while screwing the nut into the bung. Make sure it is in straight and tighten it, The finished product will look like this:

One plugged A/S bung. Since the tip of the sensor comes in contact with the exhaust gasses, you now have the possibility of hooking up an air/fuel ratio guage.:rockon:
As for sealing, the soft pacesetter washer at the bottom of the bung will do the job if properly tightened, but it probably wouldn't hurt to use some sealant on the bung threads and in between the sensor and the union part.
Enjoy.:)
