Odometer is wrong
Any help with speedometer in my 89 Regency.
Trip last weekend noticed that the MPH was off by about two miles an hour. No big deal.
When we got to the camp ground that the GPS showed 169 miles.
When wrote down miles and fuel for the trip, the odometer only showed we drove 65 miles.
About the same on the way back home. Electronic speedo to an Alison transmission.

Did you not get my reply yesterday? That is a Datcon instrument which was very popular back in the day, maybe easy to find.

Check with Miami Speedometer to see if they can change the odometer motor.

Good luck!
