CSK I agree.I run an 18 inch stainless flex fan on my 65.Been on for over 20 years and works flawless.ran a flex on my Jeep plow vehicle.Daily driver to the tune of over 100K and no problems.In fact the jeep ran a bit cold.The 65 built 440 runs 180 all day all the time.Only fan I ever saw broke was the stocker one on my 65 years ago.Rocky
