Re: Color-tune plug????

The color-tune plug is available mail-order from the Eastwood Company in
Malvern, PA.  Good catalog of general car restoration tools. Don't have
their 800 number handy but it should be readily available.  Can't remember
if they have a CO2 meter or not.  Good ones are not cheap if I remember
right.......SLM
