We stock these, they are still available from Nissan. Your local dealer can also get them. (they will probably charge the MSRP or higher)

Many states have laws governing replacing/repairing odometers.
Your local dealer may be able to send it off to be serviced (repaired) You may also check for local cluster repair shops to assit in repairing it.
Alternately, a salvage yard may sell you a cluster.
