What kind of mounting kit do I use to install a new deck into a 92' Buick Regal?

I have a 92' Buick Regal, and the factory deck is one of the 3 inch square ones at the top of the dash, below it and above the ash tray there is a 2inch tall and 8 inch long slot I can use,but do they make mounting kits for this kind of slot?|||http://www.crutchfield.com/App/Product/I鈥?/a>
