So what all is required? I've seen photos of the dash apart with what looks like the metal beam cut out to fit the double din, and a little "bridge" riveted across the top of the stereo opening, and then I've also seen photos of a whole new metal beam with the correct size opening already stamped/machined into it.
Beyond that, is it basically the binnacle, the vents, the vent housing, and the dash top?
