I notice you have swapped the flipper bases - great idea, as often the threads are stripped. You should be able to get the flipper plunger and links locally, but I know PBR stock them separately, or in the flipper rebuild kits. The sling plunger / link are no longer available - but you can substitute them with similar later Bally/Williams.
I used Bally/Williams flipper plungers on the Galaxy restore, I'm not sure if they are suitable on Ballys (last page - http://aussiepinball.com/index.php?topic=1256.90).
Take care of your back, Mitch - maybe work on the boards until things settle down. Bending over a cabinet is the worst thing you can do. Pinball will still be there after you have rested !
Well spotted Nino!! yes one of the flipper bases had stripped screws in the coil stops, they had smaller screws with nuts mounted underneath!! I tried PSPA for the bally flipper plungers and links (were listed on the website) but they were out of stock, same deal with the sling plungers which i thought might work. Never mind, i'm making my own flipper links, same as i had to for my Stern games. I have one NEW bally link to copy so it'll be sweet
And yes im trying to look after my back, back problems run in my family unfortunately.. mine isnt a slipped disc luckily, just strained muscles but its still a nuisance just the same.. come to think of it i think i probably hurt it lugging that Galaxy cabinet around the garage, was going to have that in undercoat last weekend, or so i thought, but it didnt happen..
being a muso and carrying big guitar amps around doesnt help either..
