2004 V 70 wagon

[velocespider]

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.

I 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/

Or do I have to remove the plastic panels on the post and at the side window? If yes, how please.

Thanks, Larry.
