i know what you are saying jeff, your lsc has the jbl stereo system, the panel you got was from a mark with premium sound, jbl cars have 8 speakers, premium sound only have 4, the panel you bought is from a premium sound mark so it has no tweeter grill on the top of the door panel, that long plastic trim can be removed from your door panel, and swapped onto the new door panel, the tweeter hole is on the new panel, every door panel had a hole for a tweeter, some just didnt come with tweeters. its a paint to swap the trim because the nuts are burried behind the yellow foam on the back of the door panel, you have to know where to cut a section of the foam out, i know where!! you'll probably make a mess trying to find them though!
