How do you get the dash apart to install Cd player in a 1998 Cavalier?

i have a 1998 2 door cavalier, 5spd. i never took the dash apart. to my remembrance all i did was remove two screws on the underside right above where the front change dish is and pop the bottom out a little. once the cover is popped off you'll see a bunch of hex screws holding the factory deck in place. in my vehicle i had a radio and no tape deck, remove them and the factory deck should slide out. advise getting a wiring harness, GM's wiring is shoddy. my first mistake was clipping all the wires and hard-wiring my first cd-player. good luck :)
