Keith, try to FIND an affordable copper radiator anymore. Modine got bought out by a Chinese company, kept the "brass/copper " part numbers,swapped in glued together high efficiency aluminum. Of course, the product prices stayed the same,or went up. As for the O.P.: I would run a factory fan clutch setup,find a spacer to fit. If not, the "Black Magic" electric fans ,work very well.Depends, on your budget...
