HERE IS SOME MORE INFO FOR THE INSTALL. 98 MODELS ARE THE 3-DOOR MODELS WHICH MAKES THE DRIVERS SIDE A LITTLE MORE DIFFICULT, THE SWING OUT DOOR IS GRAVEY. FIRST YOU NEED TO REMOVE THE BACK SEAT, MINE IS 60/40 SEAT THE DRIVER SIDE FLIPS OUT ON A HINGE. THE 60 SIDE WILL TOO BUT YOU MUST REMOVE TWO NUTS UNDER THE SEAT BELT BRACKET. LOOK UNDER THE SEAT YOU WILL SEE THEM, THEN TWO MORE NUTS HOLD THE BACK REST ON THEN LIFT UP THE BACK REST IT WILL COME RIGHT OUT. MINE HAS THE SIX DISC CHANGER, THIS IS BOLTED TO THE FLOOR BUT DOESN'T HAVE TO COME OUT. THE TOP PANEL COMES OUT FIRST BY REMOVING TWO SCREWS ON WINDOW HINGE. THIS IS THE TRICKEY PART THERE ARE THREE KEEPERS ON THE BACK WINDOW EDGE THAT SNAP OUT AND SOME MORE TOWARDS THE FRONT DOOR. THIS TOP PANEL MUST BE PULLED STRAIGHT AWAY FROM THE WINDOW BECAUSE THERE IS A PLASTIC ALIGNMENT POST RIGHT WHERE THE BODY CURVES AROUND YOU CANT GO UP OR DOWN ARE LEFT TO RIGHT ARE YOU WILL CRACK THE PANEL. SIT IN THE BACK SEAT PULL IT TOWARD YOU . 5X7 KENWOODS FIT FINE AND SOUND BETTER.MUCH CLEARER AND CRISPER SOUND. CHECK PREVIOUS POST FOR K JONES FOR MORE INFO ON THE OTHER 3 SPEAKERS. SORRY FOR THE LONG POST BUT LIKE I SAID BEFORE I HAVE NACK FOR BREAKING THINGS LIKE THIS BACK PANEL. IT WILL CRACK BELIEVE ME
