Lot of 8 NOS AC Acniter R45S Spark Plugs NOS Green Fire Rings (aka GM number 5613872) as shown.  Each has four green stripes (i.e. 1 wide and 3 narrow).  There is an overall box and individual boxes.  THE BOXES ARE A LITTLE DIRTY, MAY BE SLIGHTLY CRUSHED, AND ARE MARKED "MADE IN THE USA".  THE PLUGS THEMSELVES ARE NEW, BUT MAY HAVE SIGNS OF SITTING (I.E. SHELF WEAR, DUST, GRIME, AND VERY LIGHT CORRISON IN VERY FEW RANDOM SPOTS).   I purchased these on an estate sale, but I believe that they were commonly used in a wide variety of General Motors V-8's (i.e. Chevrolet, Pontiac, Oldsmobile, Buick, etc) for several years.  You will need to verify for yourself that these fit your application.  Great item to finish off that restoration or tune up.  Please see the pictures as they are part of the description.  Again, check to make sure that this will fit your application.  What you see is what you get.  Look the pictures over and judge for yourself!
