You do know the dashboard is welded in, don't you? Some years ago at a KF National I bought a complete dash for a 53 Manhattan. It was pointed out to me later that the dashes are welded in and sure enough, when I re-examined my buy that I found all the welds had been carefully cut through. I don't know how they did it, but it must not have been quick or easy. And I don't see how it could be put back in a car easily either.
