The thread on the sensor is an 18mm-1.5 mm pitch. This is the same as the
thread on most regular EGO and HEGO sensors (the non-wide band ones). Also
the same thread as on the old "F" (as in Ford) sapark plugs, as were used
on the Ford FE  series V-8's. If nothing else is handy to use for a bung
plug, an "F" type spark plug ought to do the job for cheap.

IIRC, MSD Fuel Systems (basically the same folks as make the ignitions) ,
for one, sells the 18mm-1.5 bungs (as a weld-on, threadolet type fitting.
