Dash Kit?
I had the 99-4544, and wasn't too happy with it. The sides attach via screws (which is good), however, the screws add to the width of the entire bezel. You must then wrestle it into the dash.
I went with somrthing gm-k440 from millionbuy.com , http://www.millionbuy.com/aigmk440.html
here's a pic of the kit. http://store1.yimg.com/I/millionbuy_1850_36986882 .
The sides snap in (rather tightly too), and allow for a perfect fit.
