I had the same problem. Here is what you need to do. Remove the two bolts, then you need to pull sideways. There is like 2 long metals parts that goes in with pressure, so it need to come out with pressure, one on top and the other one in the bottom.I don't know how you call those parts. If you're facing the back of your car, pull to your left. Tapping it at the same time you pulling will help. It will take some effort but it will come out. Good luck.
