To anyone who it might help........it is understood that the glass screen and display unit are glued (thanks apple) from 2013 onwards...this is true.
But you can change the screen and I am living proof...not for $900 plus due to the cost of a new display unit.... I used a screen from my 2011 imac 27 inch and yep if you look closely it hangs over a bees inch at the top which I have taped...but its beautiful and it works perfectly!!!!!!!!!!!!!!!!!!!! It is not impossible by a long shot to take the screen off!!!!
