Can you shoot me a pic?

about the same....20.5". Are you sure that yours is exactly 19" and not a little bigger? Really have to set a 2x4 at the top and bottom to get a true diameter, its tough to measure blade tip to blade tip. Let me know.

I just ran to the garage, Dmax fan is 21" in diameter. 10.5" to the center of the clutch. The problem i had with the Dmax setup is the bolt pattern on the clutch itself. The Dmax clutch had a bolt pattern of 4" on center, while my 8.1L clutch had a pattern of 3.25" on center. So i could not put the Dmax fan on the 8.1L clutch with the bolt patterns being different. I could not use the Dmax clutch because it had a 1-7/8" nut on it....to big for my pump threads. So i was kinda screwed and had to just stick with my 8.1L clutch and fan. Now, maybe if your clutch has a 4" center to center bolt pattern, i could use your clutch with the Dmax fan....but that would just be to easy...LOL. wanna check your bolt pattern?
