Then the problem is definitely within the cluster itself. From what I've heard, the parts you need to repair the odo are not available separately from Ford, so you would need to buy a complete new speedometer assembly (assuming that a 96 speedo is still available form Ford).
As an alternative, you should be able to find a used instrument cluster for less than the cost of a new speedometer. Most junkyards like to sell the complete assembly as opposed to individual gauges or other internal parts.
