everything skypilot has said is golden. you'll need a trim kit too... unless that was part of your "make up brackets". you can usually find one walmart, if not, you can on ebay. just make sure you get the right one (year and make specific)
i put a pioneer avic d3 in my 03 svtf but im not sure if our dash is the same or not. i had to use a dremmel make the unit fit.
