Did you follow the JLT video to remove the doors? I notice on my stock there are no screws or pins behind the door handle on the inside.
Just used this video - lots of similar steps. screws are exactly the same, didn't have to use any needle nose pliers as they did in the video. I didn't run into that part. YouTube - ‪2005-2009 Ford Mustang Speaker Replacement How-To Guide‬‏
