Ron Davis Radiators now has the Vehicross template and will make you a double thick unit with trans cooler. They have also made a dual fan shroud so the clutch fan can be removed.
Cost about $1100 for both.
I had thse made for California driving, but have moved to Oregon and been too busy (And cool) to install.
Mounting a trans cooler with fan will take a huge load off the radiator. I was not able to find a good mounting spot. How about inside a scooped hood insert with the top or back of the scoop cut out?
