Short Shaft Fan Clutch

I am using the 5 blade Mopar performance fan blade... this one has a huge PITCH
2.5 inch + together with a severe duty fan clutch this set up makes a Hurricane!
Never passing the 185 deg..... with a 180°F thermostat.... never
Greetings Juergen

does any one sell the fan blade? it seems that they don't sell the viscous setup any more
