The dials cannot be the same, even if the escutcheons and glass dial covers are the same. The 1965 is a 3-band radio, while the 1968 is a 4-band radio. The Radio Daze dial for the 1968 demonstrates only that they have the ink colors figured out.
I agree with Michael that you should post a WTB in the Classifieds. However I'm somewhat less optimistic of finding an original quickly. But you never know till you try.
