I have a 70 roadrunner,440,4 speed,22 inch radiator,with a shroud.I want to put a clutch fan on it,bought one from Mancini Racing at Carlisle,and it doesn"t fit.I looked up a mopar performance one at a local dealer and the measurements only allow a 1/4 of an inch between the fan clutch and radiator,not enough in my opinion.Any body else encounter this problem or have any suggestions? thanks.
