recommend getting the exhaust system hot before you try to remove it, and purchase or rent an o2 wrench, makes the job a whole lot easier

After I disconnected the o2 sensor, I just cut the wire to put a socket on it since I was gonna throw it away anyways...

Look right under you engine and right after your catalytic converter in the exhaust pipe. Should be a sensor just sticking out of there

No problem. Most people suggest o2s from rock auto. That where I got mine from.
