Hey Darin, thanks for reaching out!

The mounting holes for the Derale 17" Fan Clutch Fan # D17117 are spaced out 3" and 3-1/4" apart on center (see attached photo and video).

Hey Darin, did those mounting hole measurements for the Derale 17" Fan Clutch Fan match what you needed? Knowing how it lined up could help others checking fitment for their setup.

3 inch on center. Perfect fit for 1965 Mustang 289 with fan clutch (thermal). Fan clutch ordered from carparts.com. Great quality - all aluminum. 6 blade fan should fit. Will provide better cooling.
