SP rear-suspension U loop 
  Chaps,
 while we are all raiding the obsolete parts list, does anyone have the part number/availability/one going spare for the early 851/SP horseshoe link between the swing arm and the adjustable rocker?
 
 Alternatively, does anyone have one that I could borrow as a pattern to get the later 888/monster one modified?
 
 Cheers,
 Paul
