FWIW, I bought some 13" Be-Cools fans when Summit was running a sale. They are SPAL fans with the mounting strap kit.

I had a Champion 4-core radiator (4 x 0.63" tubes, core 2.75" deep.) The thickness of the radiator made it difficult for clearance to the water pump. Edited: tank width per spec sheet is 3.2" wide.

I changed to a Griffin (2 x 1.25", 2.68" deep core, tanks are about same width as core) exact fit radiator (about 1/2" more water pump to radiator clearance), and I used two 13" Be-cool (SPAL) fans (2" deep, 1200-1250 cfm each) on 26" radiator in '69 Coronet with 440 engine.
