When you say the hatch back, do you mean the hard plastic panel on the hatchback itself, or the felt/carpet style panels actually in the trunk?

I believe the plastic panel just snaps in/out - a plastic wedge may help removing the panel - see the Interior threads on the forum, they were discussed there, and I believe you can buy them from crutchfield. A large flat head screwdriver will probably suffice - but be careful for obvious reasons!!!
I think the clips on the felt/carpet pieces just snap in/out too.

Oh yeah, 'snap' may be the operative word - this kind of clip does not usually lend itself to being used over and over again.

Let us know how you go on - I intend to add some sound deadening soon.
