Sounds like you got one of those radiators that is simply too wide. Can you post a picture of it? I assume this is all for the car in your avatar? Tons of people have run clutch fans in these cars with zero issues. The standard two row that has either 1" or 1.25" two rows of flues is enough to cool like 700 HP in a core the size of the later A body. Was there a particular reason other than making a clutch fan impossible to fit that you chose a three row?
