For anyone else looking for an alternative removal of an O2 sensor (only if you're not going to reuse it): Destroy it down to just the nut and use a 6 point socket with a large breaker bar. 1/2" worked the best for me. Then buy a thread chaser and be done with it.
OP sorry you had issues brother. Little things like this suck the life from you sometimes. I just replaced my cat with a Euro pre-silencer. What should have been a couple hour job turned into a week long life struggle involving multiple power tools and various cutting/drilling items. I won, but the cost was high on both sides. 31 year old West German steel bolts became "one" with the exhausts flanges. Not fun. - Steve

"M18x1.5. Old Fords used this thread for spark plugs, so thread chasers are pretty available. Here's a tool number from Google: Lisle LIS12230 Oxygen Sensor Thread Chaser. I'm guessing you'll find it at your FLAPS, but it might be WAY cheaper online.
The Cap'n" I love info like that...
