8/02/64 was the last date shown for '64.
August 2nd was a Sunday, so the last full week of production would be the last week of July (07E, I presume on the cowl tag).
These are from Gunnell's Standard book of Pontiac. It doesn't say what plant so I assume these are specific to the home plant in Pontiac, Michigan.
