The new metal separator cover uses different hardware. The plastic cover used countersunk screws & the metal uses flat ones.

For the new hardware, not all 6 screws are the same. For some reason Subaru recommends installing the black screw with Loctite. Keep an eye out for that if you are doing this to your car. The black screw goes into the hole with the arrow pointing to it, presumably so you know which one will fight you the most if you need to remove in the future.
