How to take out car stereo ford crown victoria?

I have a 1997 ford crown vic and I cant get the stock cassete radio player out. I have the tools from walmart but they will not work beause the faceplate of the stereo is cracked on one side and the other side is broken so its loose. How can I get the stereo out?How to take out car stereo ford crown victoria?You have the U shaped removal tools? Then, you'll have to 'remove' more of the cracked plastic face until you can get at the four spring-loaded catches... All four have to be unhooked at the same time...
