Could someone recommend for a 66 442- fan clutch for the 19" 6 blade cooling fan?

the bolt holes measure 3 1/4" center to center

thanks-

66-3X2 442

I used a clutch from a early 80's Olds diesel. I got an AC Delco unit but they have since been discontinued. I think there is one available from one of the aftermarket vendors. My 66 never over heated in the Alabama sun with the A/C on.

Get the Hayden unit. Get a new one, they wear out and don't last forever. The Hayden Heavy Duty is what you need not Severe Duty, that's for trucks and locks up too soon.
The number is like 2747 or 2947 something like that.
