O2 sensor mounting

[Steve Ciciora]

At the local Checker Autoparts, they have a 'Help!' rack full of stuff, like 
springs, clips, knobs, etc.  They also have 'Spark Plug anti'fouler' adaptors.  
The plug screws into the adaptor, the adaptor into the head.  I cut them in 
half, grind off the plating, drill a hole in the exhaust pipe, and weld it in.  
Put an old spark plug in first to help prevent it from warping.
