radio interchange question

So let me ask this in a different way. Can you put a 68-69 radio in a 70 A body? Is the cut out in the metal dash the same? These replacement radios have a much smaller box than the originals in any case, so I don't think that interference with the case is an issue, just that the configuration of knobs, buttons and dial face is identical. From the pics of 67 next to 70, they seem the same.
