Quick Update:

I've been busy with a few bits n pieces on this pf.. rebuilt the flippers and bumpers, 1st couple of pics show the bumper switches that needed attention, 1st pic old and new bumper switch spoon, notice the hole worn in the plastic bumper spoon!! believe it or not, the game actually played with it like this, didnt notice this until i assembled the bumper bodies and the stem on the bumper skirt went thru the hole  so i bought 4 new switch spoons and rebuilt the switches as well.

3rd pic shows the rebuilt flipper mechs. new coils and sleeves, new coil stops, as well as new nylon bushes and springs. I ended up fabricating my own flipper links from fibreglass PCB material, two pieces superglued together to double the thickness to make them last longer. The plungers are the original ones. I have done this on most of my machines to replace worn linkages and it works well.
