your going to have to try more than one day for this one. It's very specific part your looking for. You'll find it eventually.

if you get pictures, you might be able to rig something else to do what it does?

actually, i think that is a huge part of that game. Without it, just a normal game.

I have the whole game for sale.

From the IPDB entry;

"A ball-grabbing device in the upper right playfield, called a 'Balligator', is activated by a 'Gator' button, located next to the right flipper button, to pull the ball into a special high-scoring lane. As the flyer illustrates, the game was initially produced using a molded alligator to jump out from under the swamp reeds to capture a nearby ball. However, the plastic alligator kept breaking on location, so this design was changed early in production to instead use a bare metal bar to grab the ball, while the swamp reeds lane plastic was redesigned to show the alligator. Only a minority of games produced have the original Balligator design."

if it's the original early production Balligator, you may be looking for a while...
