How to remove Interior plastic by back seats?, rattling starting to bug me... Options

[95CelicaST]

Does anyone know how to remove the plastic around the rear speakers? I think one of the screws that hold the speaker in has come loose, and it rattles to no end. I want to fix it before installing my coilovers, cause then it will be rattleX10.

4 10mm bolts hold the top of your rear seats to there bracket.
Bottom of the seat just pulls out.
Take out the 3 plastic panels in the hatch.
There are 2 perside 2 10/12mm screws(cant remember size) for the side brackets for the rear seat upper halfs.
take the speaker cover off there will be a Philups screw in there.
were the bottom back seat went there are 2 philup head screws.
Take off the Door seal.
Yank the panel towards the front of the car and towards inside the car.

I know I had alot of problems because there are a bunch of Push-Pin kinda deals there Red that break often, I just stole a bunch from my 94 and fixed all mine you should be able to get them from toyota or a junkyard.
