The SD has plastic gears that go bad (ebay has them), and is also an electronic speedometer.

As mentioned before the SD's speedo/odo are drive by electronics and have plastic gears for the odometer. I've done a fair amount of work on these and if you're interested would be happy to go through yours and fix it up.

Here are some photos from an 81 I worked on. He was having problems with his odometer not keeping proper mileage. Was an interesting repair. He was also interested in adapting a 160 MPH speedometer for use in his SD. I ran out of time on the project and didn't get a chance to fully figure out the needed changes.
