Mack Anthem Sleeper windows

My 2020 Anthem had the passenger side window siliconed shut as the hinge was broken. Now the drivers side has broken.
No problem, grab on at the dealer right?
All the parts are available, except,.. for the glass and hinge. If you need that, you buy the whole assembly.... are you ready.... $2200 canadian.
But they will GIVE it to me for $1650ish.
For a $300 rv window...
Anybody run into this, and what did you do? Its just a plastic hinge, im going to try to remove the whole window and see if the part of the hinge that attaches to the window can be removed, and if someone can 3d print it?
They are $300 us in the junk yard plus shipping etc.
Wondering who makes them for volvo/mack, and if you can source parts from them?
