Joined to find parts

I have always loved pinball and decades ago my husband bought a Playmatic Speakeasy for me. We moved 30 years ago and had no place for it, so it has laid dormant. Now we have a space, but it needs repair. The rubber bumpers seem to be easy to find but the mechanisim that pops the ball up by the plunger and the wires that activate the flippers are something I do not know proper names of and need to find. Also, I am wondering if some Playmatic parts are interchangeable? Please help me get back to flipping that silver ball around. Thanks so much!!!
