I mounted a 11x7 1/2x3/4 in the driver's side duct, but ended up moving it to the passenger side because it was pushing down my IC piping, but w/ out a frontmount, it should work great. You will need to work up some custom brackets to make it work right though.
Email me and I'll send you some pics of the install. I used to have them on Photopoint, but we know how that goes.

PS: You'll want to run it after the stock cooler, so splice into the line that is on the driver's side.
