Downey Header On 3.0 Auto

I've found two articles on the installation of the Downey headers but both are the manual trans. I'm looking for ideas or suggestions on the relocation of the tranfer case fluid cooler and other than the under the drive shaft crossover pipe. I like the around the rear of the transfer case exit but can't seem to figure out the placement of the fluid cooler. I know Downey make a floorboard relocation kit but really don't know how it's routed! Anybody out there got an idea on this subject or have information or pic's on your installation?? Thanks for any and all replies!!
