Another angle:
Prep as above.
Call a local mobile glass shop, let them know you already have glass and need it installed
Pay them about $100
Giggle like a school girl when it cracks because it was too close to some piece of steel and it's under their warranty rather than yours.
Yeah, I asked my local shop, which has done other glass for me, about doing this. The response was, even if the glass was delivered to them intact, since I didn't buy from them if it cracks it's my money, not theirs. I'll have the shop that is installing it supply it, even if it costs more. That way when/if they break it I CAN laugh and not cry.
