I've been brainstorming the idea of a rb1 or rb4 dvd,nav radio install in my 02 CTD but am not 100% confident I can pull it off. According to my measurments they seem to jive alright but my wifes 02 Durango which they say they are a perfect fit for has about a 1/4" wider opening and the bezel is concave shaped rather than flat like my Ram. Anybody already pull this off or no?
