what can i use to plug up my 02 bung on my tes hedders? what size and thead pitch...can i use a pipe plug?

I used an O2 plug. It is available at Summit, PN is INN-3735 and it is $8.95.
If you need it now, go to NAPA and have them pull an O2 sensor for your car, measure the threads (I think they are 18mm) and order a plug for it. If it's not on their shelves they can usually get it in by the next day. Expect to pay a little more though.
