Oldsmobile Ciera SL Dash

I have a 96 Oldsmboile Ciera SL and I have an “armored ignition” on it and I am inquiring about how to take it off… Also does anyone know how to take the dash off to get to the radio? I am replacing the exisiting radio with an aftermarket one and I also have to replace the antenna as the one on the car was snapped clean off. If anyone could help that would be greatly appreciated… Also I have looked online for armored ignition and haven’t been able to find anything the number on my window for them is 1 800DIAL911 and it isn’t armored ignition.
