I need help in removing the entire tail light lens assembly. There appear to be 4, 10 mm nuts holding this assembly onto the body. \r\n\r\nI have removed three of these nuts but the fourth is beyond reach with any wrench I have. There is a speaker in the rear post that may cover up this fourth nut; does anyone know how to remove this speaker and does it cover the fourth nut/\r\n\r\nOr do I have to remove the plastic panels on the post and at the side window? If yes, how please.\r\n\r\nThanks, Larry.
