Sorry to hear about David’s burglary.
Please remember whenever you replace side windows, pay attention to the part
number on the glass itself. You will note a suffix number after the long
part number separated by a dash (-). This number can indicate a different
thickness of the glass. In particular this is true on the X300’s. The
later models have thicker side windows than the earlier models. If you
make the wrong selection, the window will bind, or be too loose in the
channel.
