OK, so how do you guys remove the bank 2 sensor 1 o2 sensor? There is this large brace in the way, not to mention the exhaust. I have an o2 socket but there's too much play in my socket driver to get any good force, I keep running into the transmission pan. Do I have to remove this frame brace?

BTW, I have searched this site up and down and there seems to be some conflicts regarding which side is bank 1 / bank 2. I have seem it claimed and/or corrected both ways, LOL. Is this because some troopers/rodeos are right hand drive? I think that if you were looking at the engine from the front of the truck, bank 1 is on the left, and bank 2 is on the right. Is this correct?
