If at least one camera has a hot shoe: search "1/4 Inch Dual Nuts Tripod Mount Screw to Flash Camera Hot Shoe Adapter" on eBay. That setup keeps both cameras upright, and having two nuts lets you lock the cameras to the threaded rod without using spacers. Or you could get a section of 1/4x20 threaded rod from the hardware store and hacksaw it to the length you need; look in the bits & bobs drawers and you should be able to find two 1/4x20 knurled knobs to lockup on each end.
