Just got new plungers and sleeves for my FP jet bumpers for a rebuild, and when I pulled them out, I see that one might have been a little loose and rubbed against the bracket, wearing thru the wrapper slightly, and also wearing a little of the coating off the windings in a spot. Doesn't look like the coil was burnt at all, and the sleeve pulls right out, so aside from this I think it's fine. Can this be fixed easily, or do I need to solder in a new coil?

Vid, what are you using to replace the replaceable coil stop (part A-613-113) on 1981-1989 Bally pops? I can't seem to find this part available anywhere. You mentioned somewhere that in a pinch, Williams pop brackets with the built-in coil stop were an acceptable substitute, but they're a little longer......what about early Bally SS pop bracket/coil stops, like from Playboy, Space Invaders, etc.? I'd really rather use the correct part but if they're not available, I'd prefer at least the correct length bracket.

BTW regarding you last post, I picked up a Centaur recently that had a gray PLASTIC pop bumper ring! Any idea where on earth that may have come from?

Got a question, I ordered some parts from PBR to rebuild my Centaur pops and they were out of Bally plungers, so they substituted Gottlieb plungers instead which they said were exactly the same. Turns out all's not the same, they're a little over 1/32" shorter than the Ballys, and once assembled, the spring fully compresses before the plunger bottoms out against the coil stop, so there's some mechanical clunkiness going on that can't be good. It's only going to get worse as the plunger and coil stop wear. Short of cutting the spring, which I'd rather not do as it will weaken/slow the return of the pop ring, what can I do about this?
