I replaced mine not too long ago. It comes up pretty easy once the pillars are out. The light sensor and red light are mounted to it. You just move them over to the new piece. I kept my old one to look at repairing it, but mine cracked right next to the HUD which looks to be a stress point and it did not look like there was much room for reinforcement on the back. Given that I was able to find the replacement for around $80, it isn't worth it to me to try and repair the old one.
