need help anyone put a dvd player in a 65 stang?

assuming you are talking about an in-dash flip out screen, it should be pretty much like installing a din head unit. i think most classic guys get a spare bezel they can cut to fit and keep the other original. that should be it as far as making it fit, but I dont really know classics very well, is there a part of dash that hangs over the stereo? if you you will probably want to get some abs plasic or thin sheetmetal to make some sort of gap cover so you can have it not flush with the dash so the screen is viewable
