Audio Systems: cd player, ford lincoln mercury, mercury sable

Question
I have a 1997 mercury sable wagon and it still has its factroy radio/cassette deck. I took it to circiut city the other day to get a cd player put in but they told me they couldnt do it because they dont have or know where I can find an installion kit to fit and accomodate my heating controls. Do you have any suggestions as to how or where  I can get this part.  

Answer
yes  i know a place where they sale them  but did you know that you can keep your radio and add a 6 disc or 10 disc cd changer  to that radio and use the cd button
same place that carry the cd changer  have the kit
good luck
