Scott,

You can move the slot to the left or right a little, or you can cut a CA hinge in half and use it to fill the old slot on the mis-cut side. Just don't glue it in until you glue the other hinge in place. Use it was a filler, on the one side. This piece of hinge will not go across the hinge line it just stays in the one side. Leave it in there and trial fit the new hinge location right on top or below the old one. Then when you use CA to secure the new hinge in its location the Thin CA will wick into your filler piece.

This is what I did. But moving the slot to the side also works very easily.
