I used an o2 socket, then a 1/2 drive 1" socket, then a 1/2 drive swivel, then 3 extensions, to my 1/2 drive ratchet with a 5 foot long breaker bar.

Even with the o2 hot from driving the car, and SOAKED in wd40, I still managed to break a craftsman 1/2" drive extension.

PS don't use 3/8" drive, broke a swivel trying that.

That's my story, good luck.
