On this model the glass is glued to the display. So the easy repair way is to change the complete display assembly. Is there any source for a glass replacement? I was not able to source a defective display with intact glass. Is there a chance to fit the front glass from the 2012 iMac for instance on the late 2013 iMac?
I am gonna be really quick on this one, Unfortunately no, you will need a new assembly (lcd,glass) Went through the same for 4k late 2015 and after 2 years searching for something similar i just ordered a new panel and called it fixed :)
