Here's some pictures of the fan install. I went with an Imperial 16" fan, which covered more of the radiator surface but ended up having a dimple that interfered with the the water pump pulley. Since it was already set up as a pusher out of the box, and I had plenty of room in front, I decided to front mount it instead. Looking at the specs, the 10" and 14" Imperial fans should be able to mount behind the radiator and can be flipped to turn them into puller fans.
I got a relay kit to go with the fan and set up the sensor a few inches below the top hose inlet:
And mounted the relay using an existing hole in the front radiator support right next the passenger side of the radiator and battery:
