It’s hard to tell from the picture, but there has to be two blades to make a switch, so a missing blade isn’t right. It seems that would give you no pop at all, unless that game uses a relay, and then I guess you’d get a very short pop until the ball is off the skirt and opens the spoon switch.

I think you want the 60s setup GTB-B8704+ or GTB-B8549+, but all you really need is that one long blade on the EOS switch. Steve sells just the blades and contacts to make your own. You could also call him and ask what he’d recommend. I’ve never had him oversell me anything.
