5' cheater bar from my hydraulic jack handle and a large crescent
wrench did it for me with three O2 sensors.  I also used the Westy
table leg to fit over one of my box wrenches.  A pipe wrench might be
better.  Suggestions about heating it would probably help.   The
wrench has to fit the flange real tight with zero play or you will
round off the head.
