i have a 1990 civic dx hatchback and i need help with removal of the rear bumper. i apologize if there is a thread like this, i did a search and didn't come up with much. i have also lost my manual, if someone could direct me to a downloadable one that would be great. otherwise my back bumper needs to come off asap. please help

 

Easy should be 2 12mm or 14mm gold nuts inside behind the back panle just under the tail light like in the spare tire well. Also 2 more under the car behind the bumper, and last but not least the 2 on the sides by the wheels.
