The display that I received from iFixit Store didn't include them either. I swapped them to the new display by heating up the glue using a haidryer. Next step, I pulled the circular facetime camera plastic piece out with a tweezer. And the metal sensor square bracked was removed by cutting lose the glue with a razor blade. Re-apply glue on the new display!
It was pretty harder at the beginning to remove the home button as baileyswanson mentioned here. But you can loosen up the glue with an Ifixit Heat Gun or a hairdryer.
I used a hairdryer to losen up the glue under the contacts.
