Door was not closing correctly

Taking the door off was easy with a nut driver. The new parts were a little different than the original. The new part required a hole for the screw to secure the cam from turning, and my refrigerator did not have any holes, so I had to drill holes to adapt the new part. otherwise it would have been very easy. I didn;t install the shelf support stud yet, as I am trying to find out how to get the old broken one off.
