68 340 fan swap to clutch type

ANYONE WHO CAN OFFER ANY HELP/ADVICE,PLEASE DO. I AM REMOVING ORIGINAL LONG SNOUT PULLEY AND BLADE FROM 68 340 AND I AM CONVERTING TO NEW FAN AND CLUTCH. I AM KEEPING ORIGINAL STYLE[ DRIVER SIDE LOWER HOSE INLET] WATER PUMP. ARE THERE ANY PULLEYS THAT I COULD SUBSTITUTE TO ALLOW FOR THE SPACE NEEDED TO DO THIS CONVERSION[PULLEY DIAMETER IS 6" AND BELT TO HUB IS 3"] MY WATER PUMP HUB TO RADIATOR DISTANCE IS JUST ABOUT 7". ANY HELP WOULD BE GREATLY APPRECIATED.:banghead:

Damn,I wish I knew about this earlier,I'd be interested in the old fan !
