I took a look under there and it is very straight forward. Thanks again guys for all of the help. I will try to remember to take pics when I do it and post back up here.

First of all I have NOT done this!!!
but others have from what I can tell and apparently the 04 and 08 have the same setup in the hvac unit except no door and added "ribs" inside. from what I understand you need to remove the initial hvac cover get two 02 filters, use a dremel and cut out the original door bottom dimensions, cram the two filters up there and then seal it up air tight (maybe with foil tape) - the guy who originally made the kits stopped for money reasons
I'll wait for others to chime in as I'm not going to start hacking under the dash just yet...

These pics are spot on. In the first one you have to cut the plastic back to accept the filters. See the screw seat all the way on the left? That is the only screw to hold it up. the back of your plate gets notched out. I did it a heavy 1/4 inch and it fits perfectly!

Cut the plastic out. Smooth it down with some sandpaper to get rid of the fuzzies. Install the two filters. install your cover plate. get the flat plate material at the Depot along with 1" foam gasket. The 2" aluminum flatstock will take the foam gasket perfectly. You'll see, it really works out awesome. I was surprised at how well it all went together.

Anything to worry about hitting when you make the cut?

The condenser coil is up on the right but there's plenty of room. Cut away! Multitool works best
