Spark Plug Nuts (ends) For Newer Style Spark Plugs, Pack/4

Did you remove and throw away the screw-on nuts on the ends of your spark plugs, only to find out that you need them now to fit the spark plug wires you have?  Some of the newer spark plug wires require these nuts (such as Pertronix).  Some spark plugs don't come with them new, either.  We have handy packs of four available.
