I’ve been trying to find a video showing how to remove the quarter trim panel in a fastback... I’m worried about breaking the fiberglass. I want to replace the speakers that someone installed a few decades ago with something modern. Well, really I want to repair the panel to remove the speaker cutout and return it to stock... but that is going to have to wait until my other large projects are complete. Anyways, any suggestions on where to look to find how to get these things out??
