anyone have the part number for the original 7 blade fan for a 1969 camaro, 350 with A/C and auto tranny?

3947772 is the number, but remember that there was another very similar looking fan used as OE in 1969 that was not stamped with a number.

The Jerry McNeish book "The Definitive 1969 Z-28/SS396 Book" has details on page 39.
