Well today I just worked on the odometer and speedo. Like I said the original gears were excellent in the old cluster! so I took apart the cluster from the '92 that I got the other day, and I put that in my car and test drove it around worked great! no jumping 30 mph needle swings, and odometer works as well. Just a bummer that the miles is way off, any way to turn back the gears to get the miles to read what the original odometer had on it? the original one must have an electrical problem.

 

Not sure, but see if you can remove the odometer mechanicals from the back of your old speedo and transplant them onto the new one...
