How do you remove the speedometer casing in a '93 Mercury Grand Marquis?

My speedometer has a loose cable which makes it work about half the time and do nothing the other half. I know how to fix it, and i know how to get the decorative trim and instrument panel facing off, I just don't know how to get the speedometer casing itself out so I can get to the cable. Any suggestions?

How is your speedometer cable loose, since the car does not have one?
The 93 GM has a electric speedometer that comes in analog or digital.
