Just bought a '90 GT convertible. It had some cheesy aftermarket radio in it. I know most people hate them, but I really prefer the look of the factory unit. I have the factory radio and swapped it in but it looks like its missing a trim ring around the stereo. The aftermarket unit was held in with a bezel and four screws around the perimeter. That factory stereo just snaps in but looks like it should have a bezel on each side. Maybe it isn't supposed to, it just looks unfinished without anything. Are the four screw holes original or is that for the aftermarket units only? Am I missing something here? I can get some pics, I suppose that would help.
