i am taking the x-pipe off of my stang to do a t-5 swap. When i got under there i unplugged the o2 sensors from the harness and figured they'd come out witht the xpipe. well... the passenger side sensor is blocking the last nut on the exhaust flange.... do i need to buy an o2 sensor wrench to take the sensor off or is there another way? none of my wrenches, ratchets, swivels seem to do the trick. I am a Newb so please bare with me.
Thanks guys.
