Thanks!Love the colour Not sure exactly which fork you have but these guys are good for replacing elastomers.

Failing that a Manitou 3/4 fork from that era would work well as they match the geometry and new elastomers are easy to come by. A good bike shop or a bit if DIY will help you out. It can be a mess inside as old elastomers degrade needing a good solvent and clean out. There are threads on how to do this and its not too hard.
Good luck with it.
