Please advise. What is the recommended spark plug for my 1939 Bendix Eclipse TMD? Is it the Champion J6C or the J8C? or something else? Thank you. Eric
I don’t remember, but it may be a J-10.
It is a short plug to keep it from breaking the Bakelite insulation on the doors.

See if you can make sense of this plug chart. It has listings for Bendix, then refers to “Eclipse” for other plugs???
