The O-rings are included in the rebuild kits.  If you are like me you have 
consolidated all the leftover parts from all the kits you have bought and 
placed 
them in the bottom of a box somewhere in the garage.

Replacing the O-rings requires removal of the needle and needle adjuster.  
Remove the screw on the side of the piston and back off the needle adjuster 
completely to remove the needle.  The retaining screw is brass and can snap off 
in 
which case you got trouble so take great care.  With the needle out of the 
way push the adjuster out of the bore of the damper from the needle end using a 
properly sized dowel rod.  There is a speed nut (actually in inverse of the 
speed nut, it grips on the OD, not the ID) keeping the adjuster located at the 
bottom of the bore and it will take an uncomfortable amount of force to push it 
out but it will come out.  Do not loose the speed nut.  With the adjuster out 
of the bore the O-ring will be apparent and removal and replacement is 
straight forward.

Assembly is the reverse of the above. 

Good luck.
