Ouch, ouch, ouch. Sorry for your situation and predicament. But sounds like you have stand-up parental friends willing to compensate. I cannot offer an opinion on reputable glass replacement providers.
Apologies, I don't know if this is the particular spot to bring this up, but......
I'm not an A/C fan. I prefer to to drive with all windows and roof open when it's hot, and enjoy the blow-through breezy ventilation. I only use AC when I have intolerable personages aboard who can't deal with my flow-through air preferences. While making the decision to buy my ('18) Raptor I was searching for a truck manufacturer that offered entire fully-openable rear glass. Envision the Station Wagons from the '70's '80's with that rear tailgate window that entirely slid down and disappeared into the depth of the tailgate. There WAS one pickup manufacturer that offered that option, but I don't remember which (Toyota? Dodge?). All that rear cab wall space that does nothing... why can't we have a rear window that just slides down into that space, instead of this silly little sliding pocket square? Easy engineering. But there is no popular demand. Guess that's why I can't get what I want, being deep in the minority. But if there are others out there who wanted that perhaps we could at least get it as an option..... ?
