Heres how it looks after the install.

So where did the springs go? Did they replace the rubber bushings on the bottom or what?

springs went between the fan and the end of the zip tie. They're used to create tension i guess. Worked out well i think. I just used my dads grinder to take about a 1/4 inch off the top of the rubber bushings. Install was pretty easy. I used a 3/8 inch threaded plug for the bottom hole and some tread sealer. It started leaking when i put coolant in it so i really cranked the hell out of that thing. Right now the fans are wired to pull air our of the engine bay so i still have to switch around the wires yet.
