Can anyone let me know how i can take the rear lights and the rear wiper arm off my wagon. I need to take the lights off to enable me to dismantle the rear bumper, as there is quite a lot of rust to take care of on the rear bumper bar (it's rotten). The rear wiper arm is also very rusty and i would like to get rid of that rust and repaint it black. I'd appreciate the help and apologise if this post is not in the right place.
