From all outward appearances and the engine serial number(ADCA), my engine is a 1946 216. But when I went to change the plugs they were not the 10mm but 14mm plugs. The spec. book doesn't show 1-tons as having the 235 as a factory option. The casting # is 839770.
So did some PO machine for different plugs? Otherwise what plug should I now use for the "216"?
