    Scott,
    Your fan is GM # 3789562 as it appears that the clutch mounting bolt circle is 3.00" with a 2 3/8" hub hole. The fan is made by Hayes-Albion ("H" stamping). As shown in Pete's post the other fan used was fan # 3863137 made by the Schwitzer company ("SC" stamping along with the Schwitzer part number 912239 as well as a date code). I have had several of each of these fans over the past 30 years.

    Thanks Dave. Do you know what the "W" means? It appears on the "arm" of only one fan blade, on the back side.

      Scott,
      The "W" stamping has been a mystery to me for 30 years. It appears on many (but not all) Hayes-Albion fans.
