Modding the 780T side window to real glass ?

So like many I like my side window to be nice and clean, This means scratch free but seeing as all windows on the market are made of cheap acrylic they tend to develop scratches if we look at them for more than 3 seconds.



How would you go about fixing a sheet of toughened glass to it ?



Any modders out there your thoughts are welcome I usually only do interior case mods :)
