Hiz, I just saw your other post about this. Just follow your y-pipe on the passenger side. You will find the o2 sensor somewhere between the back of the catalytic converter and the place where the y-pipes come together. If it's rusted it may look like it is welded on but it's not. It sticks out of the pipe about 2-3 inches long and has some wires covered in fabric going into it.

The day before you try to remove them, soak them with some wd40 or pb blaster. And when you get ready to remove them, they say it helps to let the car run a little. Don't get the exhaust scorching hot, but get the pipes warmed up some. I personally removed mine with the pipes cold, but that is what I have heard.
But the rear sensors are easy to get to. Should have a problem back there, except for breaking them loose.
