I had the same issue when I last had my dash apart in the XE. I cut some metal strips/tabs from some gal sheet and glued them onto the dash where the screw originally went through and had broken away, then drilled a hole through the the metal tab so the screw can go through back into the factory location on the bulkhead, this acted like a washer and distributed the pressure from the screw onto the brittle plastic and stopped further breakage. No more dash squeaks and it's more secure than it ever was.
