You guys have any ideas on where to find a replacement 'close flipper' coil for a Bally Zipper Flipper assembly? This is not a standard coil - it's mounted in a metal frame with square core. My unit is shorted, but since I can't remove the actual windings from the frame, I can't rewind it myself. The part number is E-184-239. I've tried a dozen different sites that carry pinball parts, but no luck. Without it, my Four Million B.C. restoration project is on hold. Any suggestions?
