At a guess Glen !!
coupe doors would work the same way for4 door windows, I removed inner frame around window loosened window channel that door window slides in from top of door frame down to lower side of window ,undo screws that hold in window winder to door, with door widow almost up to top tilt glass to inside of car just a little and lift upwards, while holding glass up and in slide of winder from bottom of glass slider channel and window will come out of door.
Just reverse steps to replace glass.
Hope this has not confused you.
