That August date is a really early '69 SCJ and Ford had apparently not figured out all the details as they soon stopped permitting orders for the 3.91/4.30 geared cars. I have a '69 parts book that calls for a C9OE-F fan that I wonder if they ever actually made? There are some saying these really early cars had a C9OE-G and I do believe some of these exist but very few. Yours could be either of these I think. Are there numbers like you show on every blade or do some blades have something different?
The eventual "final" '69 SCJ fan was a C9OE-H, used when SCJ deliveries started up again around early Dec. '68 and used on all '69 SCJs until about late Feb. / early March when only W-codes got this fan and V-codes started getting the clutch fan.
