Tim,
The first 9N governors were cast iron with no threaded hole for an oil line. The later 9N governors were cast iron with a tapped hole for an oil line. Later, during the 2N years the governor housing became aluminum which continued through the 8N years.
As for the cast iron distributor housings, I don't know. I have some here on the shelf. I've found them scattered through all models from the early 9N through the last 8N tractors. I think distributors got swapped a lot. There were also at least 3 variations of the aluminum housings. That would be a question for Randy to research.
