Scrap them, and get Competitions.  (for fighters)
[and or Wico 8way leafs for Classics, and or Pac Man 4ways,  for 4way games... etc]
 Happs Ultimates were like their first run of microswitch joysticks.  They didnt pan out very well..  didnt hold up to the abuses, didnt control well either - especially when they wore down.  (spacer gets shreded to dust.. )
 The Comps however, are the better design, and work extremely well.  Very durable, great control. (for fighters / modern games)
