My 67 rs is a factory air car and is missing its fan clutch. Does anyone know if a hayden 2747 heavy duty will work ? I need to know if the flexalite 5718 fan will work with it . Any info would be very helpful!

I use a hayden replacement clutch on mine not sure of the #, just be sure to get the thermal clutch with the spring on the front and not the one without. The spring type will disengage when its not needed. I also read the stock 5 -7 blade fans work better than the flex. I'll try to hunt up the article with the test results....

Flexalite Brand 5718 IS NOT a flex fan, its a fixed blade fan and works great with the thermal clutch. Consider the Flexalite 5555 Thermal Fan Clutch but I am sure the Hayden version will be just fine if you can't get a Flexalite version.

Looks like the hayden clutch #2724 will work fine. Waiting for the fan blade from summit . Thanks for the info.
