The Stovebolt Site Forums The Shop Area Engine Shop Spark Plugs?

Thanks Jerry,You are a Saint,as always.
Just had to check cause the comm plugs were available and if I could use em I,d buy all he had.
Tempted to buy just a set and measure one up against a say 44 or a 45r thats on hand.
(think box whirling,thinking,eliminate extra thread length)??
