All I have to offer is advice, if you can use it, and no offense intended if you know this already.

If you don't find a good OEM clutch, a Hayden #2747 is the correct Heavy Duty replacement (got mine at my NAPA store). I'm guessing you want plenty of cooling capability for our hot California summers -- whether you have A/C or not. Also, 6-blade fans are common but I believe an OEM-type 7-blade fan is better, and they are not loud. Aftermarket 7-blades are available. I also assume you have a fan shroud.

I spent a fair amount of time researching fan clutches three years ago when the shaft seal on my original clutch unit failed. I've been very happy with my Hayden clutch.
