it's best to avoid using ZOOM twin cameras.  i don't know how many times
during my shoots that either one or the other camera wasn't zoomed,
resulting in mismatched pairs.  if you have to use zoom cameras, only try
maximun or minimum zoom.  that's your best guarantee of matching focal
lenths.
years ago i found someone who electronically connected my two olympus xa's.
eventually this caused the cameras to burn out, so be careful about
electronic fixes.
my best advice is to shoot at the highest shutter speed possible and avoid
quickly-moving subjects. practice, and in time you'll get pretty good at
manually tripping both shutters simultaneously. you don't need a "y" shutter
cable.  they don't work reliably, anyway.
one last thing. try this technique using two higher quality DIGITAL cameras.
they're already superior to film-based cameras, and you can immediately see
your results and dump those that are unsuitable. you never need to buy film
or processing.
images can be viewed using twin digital projectors (expensive right now),
converting to slides and showing them conventionally, or converted to
anaglyphs. you'll also need a computer,
anaglyph conversion software, and good photo editing software
 like adobe photoshop.
best of luck.  if you need more detailed info, feel free to email me.
