Derby....No, we did not use the Drake hub. The Drake FAN hub is a reproduction of an original 1942-'48 Ford fan hub (like the black one in the picture just above). I had one but it turned-out to be too long for the available space between engine and radiator.
Heard is the FordBarn member that owns the primered '36 Ford 3-window coupe in the picture. It has an 8BA engine in it, and the radiator leans back just like on a '37, severely limiting the space for a mechanical, engine mounted fan. Heard wanted to get rid of the inefficient and ugly electric fan which had been mounted on the engine side of the radiator.
We ended-up using a NOS Chevy Corvair fan hub like the one in the picture below. It is quite compact, yet plenty beefy enough to spin the great big cooling fan that was on top of a Corvair engine. If you like this concoction and have any more questions, I will happily walk you through any details. If you re-read the original link below-(Post #12) in it's entirety, some more of the details may come to light. DD
