I have both cars in the driveway so,..... The Cuda rear windows are round at the lower corners, where the challengers are squared. Cuda rear quarter glass is squared off where Challengers are rounded. From the side view, the door glass looks the same but I didn't measure them. Winshields look the same BUT I didn't measure them.
Don't the glass companies list Cuda and Challenger windshields and side windows as different numbers?
