1968 Windshield Glass Question --- Green or Blue?

["Eric A. Isaacson" <eric.isaacson@jbtool.com>]

Greetings,

For those with OEM Windshields, what is the factory tint?  ProSource
indicated that early Japanese cars had a blue tint where as all modern
cars have green tint.  I would appreciate confirmation of the original
tint in 1968, which may differ from other years.  Clear (untinted) is
also possible, but unlikely.

Thanks,
