Replacement Surface Pro 2 screen lacks camera bracket

The touch functionality has gone a bit wonky on my Surface Pro 2 (I get occasional “phantom touches” down the left side of the screen), so I’ve decided to roll the dice on opening it back up and replacing the LCD assembly.

Looking at the replacement LCDs available (including the ones that iFixit used to sell), they all appear to be missing a plastic bracket that surrounds the space where the the front facing camera peers out of.

I wanted to ask if a) anyone had any idea of how to swap that piece between displays, or if they knew where to buy a replacement or b) what the effect of leaving it off might be. I suspect it might have something to do with the white camera light that comes on when you turn on the front facing camera.

Any help anyone could offer would be appreciated.
