I have two fans with the exact same markings.
1. In the first picture the fan center hole is measuring 2 3/8 inches.
2. In the second picture is the fan center hole is measuring 2 9/16 inches.
3. The center line between holes on the bigger diameter center hole is 3 1/4 inches.
The center line between holes on the smaller diameter center hole is 3 inches.
4. The bigger diameter one will not fit the original fan clutch as you can see holes will not line up nor will the diameter of the hole will touch the fan bosses.
5. The smaller diameter one will line up with the holes on the original fan clutch, along with touching the bosses.
6. The smaller diameter fan is for a 66-67 big block car. Any ideas for the bigger diameter fan is for with the same markings?
