Hi guys! I just made an upgrade to my matchbox ignition. I was able to replace the factory very fragile ball bearings(what was left of them, anyways), with two full needle bearings from a Datsun b210-210 transmission(automatic is my best guess because they are flat and not round). All I had to do was to open up the hole in the middle with a grinder until it fitted onto the breaker plate where the original ones were. Guess what? No more wabbling and these bearings should last a lifetime! The Nissan part number for these bearings is, 32265-H7200. Hope this is helpful to you all! Thanks!
