I used the Stock Clutching Fan that came with the heavy duty cooling package on A bodies in 1965...View attachment 1715091435 only reason I needed the shorter clutch unit was I installed a thicker aluminum radiator... and was able to use my Stock Fan Shroud & Fan... that is also part of the heavy duty cooling packageāš“
