I have some wear in the rudder bearing(s?) on my R32.  Has anybody removed / replaced these bearings and any ideas where I can get some from or made please?  The lower bronze shoe bearing is fine, I have dealt with that previously - the wear is in the bearings in the fibreglass bonded in rudder tube.

I have removed the rudder assembly before  but never these bearings.  There is what appears to be a woodscrew - screwed into the fibreglass bonded in rudder tube - is that all that retains the bearings?  

Any ideas much appreciated.
