If you have some fabrication skills, here is a sample of what was done for a wagon lift gate, and documents the dominoes action.. I have this info here in the alternate tinkerings forum, but it's broken up a bit amongst other repairs, so this link shows the lift gate repair/fabrication in it's commercial free entirety. Hope it helps..
