Old Fox Vanilla Float service kit

[lowslowandold]

Having just rebuilt my fsr I noticed that my rear shock is weeping and very slow on the rebound, so I think it needs a full service, but where can I get the parts to service it, fox sell a kit that service every rear shock since 2000, but I think mine is pre that? Any help would be great or some one I can call?

Can post pictures if required
