I rebuilt the lower hub, replacing the bearings, which I got from Irvine Bearing. I think it was classified as a permenantly lubricated bearing off of an air craft. There should be a bearing number on it.
The upper bearing I have not done, but assume it to be the same store.
The hard part will be finding the top swedge for the Cable, which is slined to line up the shackles of the jib.

I saw the posts on the subject explainig that its fully serviceable and spare parts may be still available but if you have any information on how to do regular service and lubbing it will be very helpfull, I have the advantage that since its a small Macgregor 26 Classic I can lower the mast with ease to service parts.
My first concern is the upper bearing for the stay.
