The replacement display has a lower depth than the original and consequently ends up slightly further away from the front glass. To get it closer to the glass, I cut away the LCD PCB where the mounting holes would have gone. To mount the LCD, I created a mounting plate to which the LCD's PCB could be attached.

In retrospect, I do not think getting the display closer to the glass worth the trouble. It does not make that much difference and means a lot of additional work. Rather than bothering with cutouts and a mounting plate, simply drill the LCD's PCB in the appropriate locations and mount it directly.
