Looking at the breakdown of the display, I'm not sure I believe that seller about those hinges.
The Acer part numbers for the hinges are
Left Hinge 47.4WD07.001
Right Hinge 47.4WD08.001
It looks like you would have to pull off the back frame (7) because the front (10) is the LCD module.
This looks like it wouldn't be worth it.
