  Yes, wiring the bolt does sound like a good idea.
  
  In my case, I have slight elongation of the holes in the tab and no wear in
  the alloy link piece (I don't think it is merely aluminum).  Like Chris, I
  found that regular replacement of the bolt "tightened" up the whole
contraption
  somewhat.
  
  Were I to use a bearing, it would have to extend through the tab holes so
  that the bolt/nut would tighten against the bearing, leaving enough
"looseness"
  so that the link would be able to freely pivot on the bearing, but the tab
  would  be held firmly.

[Don Gordon and I have been talking about this for awhile and are probably 
going to incorporate the bearing fix into his LNC2 in the near future. 
 Allowing the bearings to prorude through the tab holes and tightening to them 
would suggest that you want the link to rotate around the bearing, rather than 
allowing the bearing to rotate around the bolt.  I don't think that's the best 
solution, as now the wear surface would become the area at that thin edge of 
the tabs instead of the inner surface of the bearings against the bolt.  It 
would be better to press-fit the bearings into the o/c link so they can't spin 
in the link.  Additionally, press fit flanged bearings into the tabs on the 
strut and allow them to extend inboard far enough to remove any axial play in 
the o/c link itself.  Tighten the bolt to capture the flanged bearings in the 
tabs and safety it so that part of the assembly becomes immobile (ie, no 
rotation of any kind at the tabs).  The edges of the link bearings will rotate 
against the inboard edges of the flanged bearings (flanges outboard, facing 
the bolt head and washer/nut  on the other end) with no axial play.  The link 
bearings will rotate around the bolt making the interface between them the 
only wear surface, one that is easily renewed with new bearings when required.
