Window sizes

Can someone please tell me when the rear window of all beetles from oval leading up to supers have changed.
In between the oval and super what were the rear window sizes and what were the years?
Cheers

Australia changed at different times to the rest of the globe.

57-67
68-71
72 onwards

are the beetle rear windows.
Supers and standards all used the same glass it was only the windscreen on Lbugs that was different.
