I have an 81 Z28 that I am trying to remove the dash bezel to get to the back of the gauge cluster to change speedo cable. I have removed all the allen screws, the cigarette lighter wiring, and wiring for the dummy lights that are attached to the bezel. It is loose all the way across until you get to the head light and wiper switch. I also removed the nut on the headlight switch so that is loose. It acts like the wiper switch is holding it. Any help would be appreciated.
