Which year of the Ford Mustang Fastback had the longest sloping rear window?

The actual length of the window itself is nearly identical from 69 through 73. The 69 and 70 roof has a little steeper angle to it.

Im trying to figure out which year had the longest rear window. Which year would that be? 1969? 1970? 71? 72? Etc, etc. All help is greatly appreciated.
