Default Off road Y-pipe O2 hole question

Ok, I have a Mac offroad Y, and for some reason the plugs that the rear o2s would go in, are open. they were not sealed off with bolts. Does anyone know the thread pattern of the 02 sensor so I can just thread a bolt into it to stop the hissing/whistling exhast leak from those two rear 02 holes. I have sims and I am not worried about that, but I need to fill those 02 holes. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Thanks.

Both MTI and Thunder Racing sell them. I gave up trying to match the thread pattern and just bought.

Cool! I just talked to my local muffler shop as well and he actually stocks them for our cars aslo as he does so many F-body set ups! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
