I have a cracked tail light and purchased a used replacement. For the love of German engineering do I need to remove the shelf and Monsoon amplifier to get to one of the nuts? If so, how do I get to all the screws as they appear to be in hard to reach places without removing the interior trim? I saw a thread where drilling a hole in the plastic was on option, but not sure how to drill a large enough hole in that spot. Anyone been through this? Doesn't help that it is 28 degrees in NJ and I have no garage to work in. Thanks
