I thought that too at first Adam but my `68 has a standard fan. Then I found references to a standard fan and a clutch fan. From what I can find it looks like the fan clutch was found only on A/C equipped cars but I`m not sure. I have an early 68 340 that has just the standard fan and I`d like the benefit of the fan clutch but only if it was correct for the application and year..
