What you have is a 1995/1996 era Judy. This was the fist generation Judy, OEM spares are long OOP, there limited number of aftermarket options available like https://www.suspensionforkparts.net/...95-96-all.html.

Unless you need period correct fork, would thinking that selling this to someone who has experience with this generation fork, and replacing with a better performing current fork would be a more cost effective/give you a much better ride option, as elastomer based forks really are a dead end technology.
