I think Charlie is right. these fans are rarer then I thought.
Today I got to the warehouse to look at clutches for a few people.
I have eleven 5 blade fans from that time frame.
2 of the fans have 4 rivets like this one, 6 have have 5 rivets, and 3 others have 4 rivets in a box pattern with a square blade mount.
Other than that they all look and measure the same.
Does anyone know the reason? Some appear to be earlier, and some are later. I can tell this because of the original clutches that are mosty still attached.
Does anyone remember the particular applications?
Not all of these came from Chevy, so some have the larger spacing.
Since I only had 2 of the rare ones, they especially would not be for sale.
