Apply new adhesive to the back of the LCD face (otherwise there will be a little rattle).

I used standard double-sided tape.

I folded it lengthwise to thicken it, and trimmed with a razor.

If you look closely, you will see light markings where the tape should be applied.

(sorry about this last photo,iFixit makes the crop 4:3, which cuts off the image... Ill try to replace next time I replace one.)
