Dave, if you can't get a replacement try this.
Crazy glue the cracks, as best you can. Then insert a bit of a wood matchstick into the screw hole, crazy glue again, set aside till hardened. You should be able to make a small hole in the middle of the matchstick and the old screw should be able to bite in and reseat firmly.
