Paul,
 
In my humble opinion, the problem has nothing to do with the fix.  The problem is often overdriving of the down cylinder into the overcenter link.  The resultant force acting on both the overcenter link and the cylinder attach end caused the damage.  Decreasing the stroke solves the poblem. 
 
Additionally this may also require the close scrutiny of the slidding sleave which acts as the up stop.  I've used many thin washers to help assess the proper up travel- Then machined the sleave to "perfect" length.  A few thousandths of an inch is significant in the length of the up stop.  A 1/2 turn on the down clevis is also a significant amount of travel.
 
The fix, on the other hand, I'd assume folks are putting an 8 or 10 bid strap over the nose tunnel.  Not sure how much glass, but do know that no amount of glass will be enough if the strut is still in compression when "apparently" fully extended and overcentered.
 
Note- Check also for overcenter link hole wallowing.  If there's been too much force, it'll show unpleasant wear.
 
Good Luck,
