Pete,
I've had good and easy results using plastic wall anchors in situations like this. Another way was to use a dab of epoxy putty, the stuff that comes in 2 colors to be kneaded together, on the back side of the hole and redrill for the existing screws.
On a separate note, when reinstalling self taping screws it's good to start with screwing in the wrong direction, when you feel where the threads pass the start, sort of a click, then turn the right direction. The purpose is to put the screw into the threads that have already been made and not make a second thread.
Hope that helps,
Jim
Here is just one brand. It's easy to find in most hardware stores or Amazon.
