65 Barracuda Factory Fan?!

I couldn't fit a clutch-fan in my 273, not even a thin one for a 1980's M-B 300D (but does bolt to water pump). But, I don't have a factory radiator. Even if OE, I'm not sure an early-A has room for a clutch-fan. A 1990's Jaguar clutch-fan is also popular with rodders since thin. Best are clutch-fans with a thermostat on the front. I think the others don't adjust with temperature.
