My after market car stereo was stolen a while ago but the car kit (black plastic piece stereo store put in to make it fit) is still in and im not sure how to remove it. i want to reinstall my stock radio and i shouldn't have a problem with that. could just use a little info/advice on taking out the car kit so the stock system will fit again. the car kit seems to be anchored behind the console and i shouldnt have to rip allthat out right? please help thanks.

it is a 93 jeep grand cherokee laredo
