I did mine in my 98 SE that had theftlock. I didnt have any problems . as far as screws, I
dont think they had any. It has tabs on the back that fit into holes. Make sure the first thing you do is thak you the fuse for your aibag.Then remove the neg cable from battery.
What you do is look at the whole plactic peice that surrounds the radio. Im sure youLL see that it bigger than that. Mine covers the instrument pannel, radio and a/c, it one peice. Take a screwdriver and insert in in the gap, and pop thearea out, follow it around andit should come off pretty easily.
Once thats off, you should see about 3-4 screws holding a plate that keeps the radio in place. take those out. and remove plate.
Next is to pull radoi out and unplug the conectors out and antenna. The radoi just comes out. now your ready for the new one, follow the instructions on kit and radio.
the install ove plate, and others is reverse of taking them out.
