Depends on how you made the original bracket.  I've made two such brackets out of wood and solved the problem differently in each
case.

1.  I mounted two small point and shooters on a 1/2 x 1 inch board by just drilling holes through the board where the tripod screw
holes are on each camera, counter sinking the screw holes.  I keep them aligned vertically with a flat 'propeller' screwed into
the back of the mount board.  Turn the propeller perpendicular to the board and it acts as a back plate to keep the cameras
aligned.  Took a little fiddling to get this to work.  And I chose cameras with flat backs precisely because I knew from
experience this would be a problem.  Not perfect, but it works well enough I haven't felt it worth improving.

2.  I mounted two big old SLRs to two 1/4 x 2 inch boards, hinged the long front edge of the boards to allow for toe in on close
ups.  The boards are wider than the camera bottoms are thick, so I keep them aligned with two small wood chips -- 1/2 x 1 inch
roughly -- glued to the boards.  Works perfectly.
