Might be worth keeping an eye out for a replacement. Risse may still supply them, I think they were called 'gem' dampers. White bros also did after market upgrades or if you can find some, englund air damper replacements will make your judy as good as they can be, but are rare and cost £££££.
28mm Sid internals also fit iirc.
