Notchback rear glass.

Any thing is possible but I HIGHLY doubt any of the previous owners would have replaced a big part of the car, they Mickey moused the SMALLEST most insignificant things that I don’t see them doing a big project like that. Curious to know if ALL 68’s came with the drilled holes. Either way we’re gonna get to drillin to install. So the car will be whole again.
What is the build date? Maybe early '68's still used the '67 type setup.
