I guess you could either take it to a mechanic and have him fix it or drive it as is and just change the oil every 2-3 months and not rack up any miles on the odo.

The odometer on the 84-91 model is analog not digital like in the newer models. The odometer is driven electrically by the same signal the speedometer is so it's probably a problem on the electronic board or the little electric motor that runs it..... You will have to take the dash board apart and check it from the behind the instruments.....
