If I am correct that vehicle uses a speedo cable that goes from the instrument cluster to the transmission.
If your speedo is not woorking you may have a bad cable or gear which is on the end of the cable and can be accessed by removing cable from tranny which is held in by a bolt and clip.
If your speedo is working but your odometer is not than you have a problem in the cluster itself.
You can have it repaired at a certified speedo shop or replace it with junkyard unit.
