Flex and clutch fans

OK Stroker I am going to make an attempt to answer your question on this fan.The width of the fan where it bolts to the clutch. hole dia. is approx. 2 1/2 " around. clutch dia. is about 6 1/4 " on the big side. If this isnt what you need, let me know a little more and I will measure more. Thanks,Bill
