Spur Gears, Helical Gears, Miter Gears, Worm Gears, Worms, Anti-backlash Gears, Anti-backlash Worms and Bevel Gears from SDP/SI

Maybe one of those gears will work. Its hard to say as I've never seen/worked with the gears you're looking for. Grab a caliper, take some measurements and maybe you'll find something compatible on there.
