I have used Hayden as an aftermarket cooler. I would try to find a trans cooler from a trailer tow or police package car to keep it all Ford.
A Hayden is an easy install. It has long plastic pins to secure it in front of the radiator. Make sure you flush out any used cooler before you install it.

The aero ones are probably a bit better than the box coolers. The aero's are plate coolers and are a bit larger.
