Trans cooler. Type, mounting help, TTI headers

I have a 408 with a 904 trans, and need some help on picking out a very good cooler as well as help in how to run the lines around the headers.
I want a stacked plate design, and i am looking at a Derale 16 row, or 25 row cooler. They come with an6 fittings, the 25 row is rated 45,000! Btu. I want a system that will keep the trans cool without having to pass through the radiator.
Any pictures of mounting brackets and routing of the lines would be great. Thanks!
