I have an inventory of various vintage AC Spark Plugs. I would like to know if there is a reference source for the application of these plugs. The inventory includes the following : 10 - #43L: 6 - #44-5Com; 23 - #42S; 13 - #C42Com; 11 - # 84TCom; 7 - #C43; 8 - #85TS; 8 - #84T;32 - #44Com; 32 - #85T; 8 - #45M.
