Can anyone recommend a source for the self-locking nut, P/N MS20365-516C, used to secure the split nose wheel halves together? I have a 1965 Skymaster, and this P/N comes from the 1965-1968 IPC. I haven't found a source for the -516 size nut, nor an alternate P/N. The folks at military-fasteners.com, to whom I was referred by Aircraft Spruce, could not source it. They suggested it may have gone out of production, replaced by a different part number. Or, does anyone have a later edition IPC which might show a different P/N for this nut? Any help would be appreciated. You can email me directly at
acmechanic@protonmail.com if that is more convenient. Thanks!
