'87 has a manual speedo, meaning it has a small gear in the tranny, connected to a cable that runs from the tranny to the speedo. The cable spins the speedo and viola!. Anyway, if it doesn't work it either doesn't have small gear in the speedo or the cable is broke or frozen. Those are really the only 2 things I would think it could be.

I would check on that, cause the speedsensor does determine your miles per hour, it's a mechanical speedo.
