Next, you'll have to pull off both of those big plastic pieces that cover the C-pillars. The spring clips are really strong, so try not to leave any white "stress marks" in the plastic as you pull off the piece. This is what it will look like:

Then, pop out the little plastic ring that goes around the trunk lock on the rear deck itself. Now pop out the rear speaker grilles. They're also held in with spring clips, and I've found that it's actually easier to use a pair of needle-nose pliers and push the clips out from the underside.

Next, pop out the little plastic retaining pins that hold the trim pieces on either side of the opening for the pass-through (there's only one for each side). Then pull the trim piece toward you as you pull the edge of the deck upward (and out from behind the trim piece). You're left with this:

You'll notice that there's a metal clip in the very center of the front edge of the underside of both decks. There's a white plastic pin that slides into the metal and attaches through a hole in the body below the deck. It may or may not have come out with the deck. Remove it either from the body or the deck (depending on where it ended up) and slide it into the metal clip on the new deck. There is also a metal piece on the underside of the rear of the deck. It's actually a little tongue that has to slide into a groove in the body right at the edge of the window.

Position the new deck approximately where it should be, and then slide the tongue into the groove to lock the rear of the deck into place. Then pull the trim pieces forward again and tuck the new deck back behind them. Push the white plastic pin into place to lock down the front of the deck. Then re-assemble the interior in the opposite order in which you took it apart.

It took me longer to type these instructions than it should take you to perform this mod... it's really simple.
