Fixed Odometer, now Speedometer Reads Wrong
Looking for some guidance. I replaced the plastic gears in the odometer and got that working. Unfortunately my speedometer is reading 35 mph when I know I'm running 55 or so. Anyone know how to get it to read right? The car is an 87 TA GTA. I don't know if there would be any other info needed. Any assistance would be appreciated.

Is the speed offset the same amount all the time or is it off by a percent ratio at all speeds?
