I was able to push the bottom part of the shield to the left and unhook the bottom first. I then took a long wooden skewer (18" long) and pushed the center pin out. I then took a pair of needle nose pliers and gripped the two flared ends of the outer sleeve and squeezed them together and pushed the sleeve out of the hole. It was actually pretty easy this way and there was no damage to the pin or the sleeve.
