Mongo's original glass is taller than yours and fit his cab

AMD is going to refund yours once you break it, that sounds like a free pass to me, at this point they'd be happy if you got it installed and they did not need to refund.

So try installing it before you break it? Maybe it sits in front of the pinch weld.
or break out the belt sander and try making it smaller. Nothing to lose

There was lots of weird 'safety' stuff tried with auto glass back in the 50s and 60s, keeping passengers from being ejected, keeping broken glass from going into the car.....eventually leading to windshields glued to pinch weld starting in early 60s. The first one piece and curved windshield for GM truck division maybe was weird too
